Since you clicked on the Dolphins, I guess I will tell you a little bit about myself.
Better click the back button fast because this has nothing to do with work.

Born and raised on (and in) Mobile Bay-(pronounced Moe-Bill dagnabit!)
I joined the Navy when I was 17, yes-straight out of high school.Why you might ask…….none of your business
-just kidding
Did not have any money to go to college and I partied too much in high school to get a scholarship, there-you happy!!!
Why did you choose the Navy-(boy do I hate nosey people…)
I went to the four branches (sorry USCG) and researched their hardest programs-mental programs-I am no SEAL…
Newsweek rated the Naval Nuclear Power program as the hardest collegiate program in the US,
(Higher than MIT-a fact that makes me very proud.), with a strict entrance process and a 75% attrition rate, I knew it was for me.
After learning how to glow in the dark I volunteered for Submarine Service.

that makes me a Sub-Mariner not a Sub-Marine-er
I was lucky enough to be chosen for the best Sub in the Navy-no joke.
A fast attack spec op (special operations) boat out of Hawaii, we consistently scored excellent on our ORSE exams (rare to say the least) and consistently received the Battle E.
“We were the S#!&” to put it in nautical terms.
Been through every longitude and 3/4 of the latitude, we got around.
I had the pleasure of working with numerous specialized groups and the best of the best.
If you are one of them-it was my extreme honor to work beside you.

Very family oriented, so after the Navy I went back home.
I have two sisters, of whom I am very proud and have the utmost respect.
One is a CPA who has her own firm, Karen C. Simmons, PC and the other who owned her own business, which she ran with such diligence and pride that it astounded me.She recently sold the business so she could teach at her kids private school. They both amaze me. Not bad for three kids who grew up dirt poor on the Parkway.

Immediately upon my honorable discharge I started at the University of South Alabama, a very underrated college.
Three years later I received my BS in Mechanical Engineering. (yeap, three years 🙂 )
I was inducted into Pi Tau Sigma (an engineering honor society-must be top 3%) and missed graduating with honors by a very very small fraction (thank you very much Dr. Zheng!!!-can’t follow my work my arse-I was always the first one to be done and the answers on both finals were 100% correct…. ohhhhhh….uuuhhhgggg… the agony.. haunts me to this day)
I wanted to get a tri-major in Physics and Math but the Dean of Engineering would not let me get co-majors while getting my BSME, Department policy :(.I was set to go for my Masters/Doctorate in Engineering, however, that was side tracked when I met my wife.
Who would Marry me- YOU GO TOO FAR!!!
Who-The most beautiful and talented woman I have ever met (wife’s addendum- “or will ever meet”).
She was the lead singer for a regional rock group (she plays piano, horn, guitar etc…which fills the house)and I instantly fell in love the first time I met her and I’m smitten to this day (even though she is more than a little crazy).
-I know-kissy kissy goo goo – get ready-here comes more
her inner joy for life, her spirit have taught me more than I will ever admit. She unwittingly guides my life, my character and gives me true meaning.

ok, back to being a man–
Fate being a kind friend, while I was still in school, I was sought out by Marine Exhaust Systems of Alabama and I could not ask for a better job… BUT DON’T STOP ASKING.
I was starting my senior year when I started receiving calls with job offers.
I interviewed at Marine Exhaust and knew it was destined to be. Felt right.

Challenging, engaging, and believe me-none stop, day and night. Every facet of every job I think.
Sales-which I never thought I’d do and better yet, never thought I’d be good at…(People really appreciate my frank honesty-I won’t and don’t Bull$#!*), Design-which I truly love, Marketing, Advertising, Purchasing, Quality Control, Research, Technical Support, Network Administrator (I put our network together-fun stuff)and much more (not to mention the fun I get to have building and maintaining this web site)
Every day is worthwhiled and exciting
The OJT given to me freely (and daily) by our superior machinist, welders and fittershave become invaluable. If you have talked to me on the phone, you know how I brag on the superiority of our craftsmen.
Shortly after meeting my wife and landing the perfect job, not shotgun short but there was no time wasted if you know what I mean-and I think you do, we had our first daughter.
The second joy of my life-(1st joy being my wife, Family First always)-and she is just like her mother. Brilliant and Beautiful, she scored Post High School on on her second, fifth and sixth grade SAT’s!!! and now in 7th grade she has scored high enough on the ACT to actually get into college 🙂
A couple of years after our first daughter was born, we had our second girl, another miracle and yes-still just like her mother–thank God. And yes she scored post high school on her second and fifth grade SAT’s as well!!!
I love them soooo much!! They have sooo much of their mother in them-how could I not, and both are way smarter than I will ever be…

Somewhere in between our two kids we found the perfect dog, and I do mean perfect. A gift from God, true member of the family.

Heaven just got a little brighter…She passed April 2009-may she rest in peace.

Now, My wife finished her Masters in Speech Pathology at South with honors and started her new career, so very proud.
All through grad school, she did not make anything below an A!!! and moving forward I truly feel she has found her calling 🙂
Me, I am now the owner of Marine Exhaust 🙂 and I have plans to get my PE License some time in the distant future-this may be impossible as I have no PE to work under…) and I plan to go back to college for my MBA, CWI and masters when my wife lets me. (Maybe get Marine Exhaust to pay for it…JUST KIDDING… wink wink)

Well-that’s me or atleast my perception of me. I love my family and my job, life is good.
and now to play with some more PHP :)]]>

Maxim Silencers, Inc. – Operating Instructions



Installation & Operating Instructions

Exhaust Pipe Length

To prevent unsatisfactory performance due to piping resonance or shock waves that can develop in the piping between the engine and the silencer, it is recommended that the silencer be installed as close as possible to the engine. The exhaust pipe length between engine and silencer should not exceed fifteen times the silencer size. For example, a 6” silencer should be installed within seven and one-half feet (90”) of the engine. If the above recommendation can not be followed, the customer should discuss the installation with Maxim.


Exhaust System Expansion Joints

For most exhaust systems designs, it is necessary that an expansion joint be installed between the engine and the silencer. This will allow thermal expansion as well as reduce the amount of engine vibration transmitted to the silencer. If a short exhaust system with no expansion joint is desired and the silencer is to be supported directly on the engine flange, the silencer inlet should be provided with gussets.


Flow Arrow

It is imperative that the exhaust gas flow in the correct direction. All silencers are equipped with nameplates that show the correct flow direction.


Spark Arrestor Orientation

On spark arrestor silencers, the silencer body is equipped with a box on the side that acts as spark trap. If the silencer is mounted horizontally, the spark trap should be on the underside. If the silencer is mounted vertically, the orientation of the spark trap is discretionary. The purpose of the couplings on the spark trap is to provide access for cleaning purposes.


Support Methods

The silencer may be supported by the inlet and outlet flanges, provided the piping on both ends of the silencer is equipped with lateral supports or guides to prevent large bending moments from being transmitted to the silencer flanges. The following flange loadings are the maximum permissible for most installations. Do not load beyond these limits: Axial (in a direction parallel to the nozzle axis): A force equal to the silencer weight. Shear (in a direction perpendicular to the nozzle axis): A for equal to the silencer weight. Bending Moment: The silencer weight multiplied by the silencer size. For example, a 12” M-51 which weighs 1,295 lbs. can withstand the following nozzle loads: axial: 1,295 lbs., shear: 1,295 lbs., bending moment: 15,540 inch-lbs. Contact Maxim for additional loading information.


For those installations where the silencer is to be supported by the inlet only, the user should install four stiffener gussets on the inlet nozzle. These gussets should be welded to the flange, the nozzle and to the silencer end head. A special silencer with factory installed gussets may be ordered if desired. Likewise, if the silencer outlet is to support a long tailpipe with no lateral support, the outlet nozzle of the silencer should have gussets. A tailpipe of maximum length equal to six times the silencer size may be supported free standing without gussets. For example, a 12” silencer without gussets can support a 72” long free standing tailpipe.


For horizontal silencer installations, the silencer may be supported by factory installed saddles or bracket supports. However, the user may choose to support the silencer with two body bands, which are attached to overhead hanger rods. For vertical silencer installations, the silencer may be supported by factory installed legs, trunnions, or bracket supports.


Silencer Common to More than One Engine

It is recommended that a silencer never be connected to more than one engine at a time.


Water in the Exhaust System

Design of the exhaust system must be such that water is not allowed to flow back into the engine. Silencers are not specifically designed to prevent the flow of water back into the engine. With some configurations, the silencer body may become a water trap and for this reason, drain couplings are provided on some models. However, the presence of a drain coupling does not mean that the silencer will prevent water from flowing back into the engine.


Insulation of Silencer Body: Caution!

A typical engine exhaust system has gas temperatures between 500°F and 1,200° F. A typical uninsulated silencer will have an outside skin temperature between 400° F and 900° F. An approximate value for the amount of heat transmitted through the silencer walls is 2.0 BTU per hour per square foot of surface area per °F difference between the gas temperature and the outside air temperature. In view of the above considerations, the user often elects to insulate the silencer body to either reduce the external skin temperature or to reduce the amount of heat transmittal. However, insulating the silencer body will mean that the silencer shell temperature will be almost as hot as the gas temperature. Since carbon steel scales and deteriorates very rapidly when its temperature exceeds 1,000° F, the user must be aware of the possible consequences of insulating a silencer that operates with gas temperatures above 1,000° F. Stainless steel construction is advised under these circumstances. If burn protection of personnel is the main reason for insulating, the user should use an expanded metal safety shield rather than insulation.


Pressure Testing

Unless specified in the customers purchase requirements, a silencer is not pressure tested. If it is mandatory that absolutely no leakage is to be permitted, the silencer should be purchased with specifications requiring pressure testing at the factory.

Maxim Silencers, Inc. – Quick Reference Guide



Older Model Quick Reference Guide


In simple terms, silencing is the act of reducing noise to an acceptable level for the location or working conditions surrounding the noise producing equipment. MAXIM’s money saving line of stock silencers readily solves noise problems of many applications. Comparison of the typical attenuation curves for individual silencer models will show the relative capabilities of different designs.

MODELS M21, M31, M41, M51 AND MUL

Chamber type silencers provide the best noise control across the entire audible range. The basic design incorporates non-resonant side tube arrangements to permit passage of the exhaust gases from one chamber to another. This creates a reversal of flow and develops a predictable amount of back pressure. Another important feature of chamber type silencers is the availability of side inlet exhaust connections. Units of this type, except for spark arrestor designs, can also be supplied with side outlet exhaust connections. These side connections, while having little effect on the pressure drop, will in many instances, greatly facilitate installation of the silencer by eliminating the need for elbows in the piping.


M21Good chamber type silencer. Use in areas where background noise is relatively high and constant and the need for higher degree of silencing is minimal. Expected attenuation is 17 to 20 dBA.M31Better chamber type silencer for residential areas where background noise is present but not objectionable. With expected attenuation of 20 to 24 dBA, the M31 is intended to bring most exhaust noise levels down to match the ambient noise levels.M41Excellent chamber type silencer. Use an M41 in quiet residential area where background noise is relatively low and critical grade silencing is desired. Expected attenuation is 24 to 28 dBA.M51Best chamber type silencer for “Hospital Grade” silencing. Use an M51 for the highest degree of silencing for areas requiring the maximum noise reduction available from standard chambered silencer design. Expected attenuation is 28 to 32 dBA.MULThe MUL is comparable to the M31 for pipe thread sizes 1″ to 31/2″. COMPACT CHAMBER TYPE SILENCERS

Compact design is engineered to provide a “critical” grade of attenuation while minimizing space usage. Excellent application for packaged power and process skids where space is a
premium. Dual inlets and other custom designs can be easily incorporated.  Low Temperature design not only reduces skin temperature, but radiated noise as well.  Heavy duty, welded construction with temperature resistant insulation within a double wall construction. The inlet and outlets are standard with ANSI drilled 125/150 lb flanges. Standard finish is high temperature resistant silicone black. Alternate finishes may be available upon request. Standard material is carbon steel. Stainless steel is optional.


MD26Expected attenuation is 28-32 dBAMD36Expected attenuation is 33-37 dBA



Spark arrestor silencers have application in marine service, refineries and other hazardous environments. These are chamber type designs. Theretention of hot carbon and soot particles minimizes danger and helps to provide a cleaner area and atmosphere.


MSA1Highly efficient spark arrestor silencer with M21 attenuation characteristics. Expected attenuation is 17 to 20 dBA.MSA2Highly efficient spark arrestor silencer with M31 attenuation characteristics. Expected attenuation is 20 to 24 dBA.MSA3Highly efficient spark arrestor silencer with M41 attenuation characteristics. Expected attenuation is 24 to 28 dBA.MSA4Highly efficient spark arrestor silencer with M51 attenuation characteristics. Expected attenuation is 28 to 32 dBA. 


Straight through silencers have an unobstructed passage through the silencer with no reversal of flow. The result is a pressure drop across the silencer only slightly above that caused by an equivalent length of pipe. Side connections are not practical in this design due to increase in pressure drop and price. Since noise attenuation provided by straight through design is less than that provided by chamber design silencers incorporating a reversal of flow, the MT series is best used in applications where low pressure drop is the primary consideration.


MT21For noise control applications requiring low pressure drop. Expected attenuation is 13 to 16 dBA.MT31For average attenuation of objectionable noise where effective though not complete silencing is required with low pressure drop. Expected attenuation is 16 to 19 dBA.MT41For better than average noise attenuation with low pressure drop requirements. Expected attenuation is 19 to 22 dBA. 


Constructed of stainless steel, the MAXIM MP series silencers are available for wet marine engine exhaust applications. Water is injected upstream of the silencer in sufficient quantity to reduce the exhaust temperature to a maximum of 200o F. The MP-11 may be installed in series with an MP-31 or MP-41 to provide additional attenuation.


MP-11Low pressure drop with good performance. Expected attenuation is 15 to 18 dBA.MP-31Medium pressure drop with better performance. Expected attenuation is 20 to 25 dBA.MP-41Highest performance for a wet exhaust application. Expected attenuation is 30 to 35 dBA. 


The MAXIM VT series silencers are designed to attenuate high frequency noise associated with venting of high pressure air, gas or steam to atmosphere. These ruggedly designed silencers feature all welded construction with concentric acoustically packed panels.


VT-1Good vent silencer for controlling noise generated by pressurized gases released to atmospheric pressure. Expected attenuation is 35 to 40 dBA.VT-2Better vent silencer for controlling noise generated by pressurized gases released to atmospheric pressure. Expected attenuation is 42 to 45 dBA.VT-3Best vent silencer for controlling noise generated by pressurized
gases released to atmospheric pressure. Expected attenuation is 50 to 55 dBA. 


Intake models are built “cleaned for intake service.” The FPE model in stock sizes 4″ through 12″ is also built clean for intake use and may be substituted for the FP. The “E” designation on any FP design indicates that the silencer is built to withstand hot engine exhaust service.

Absorptive silencer designs are compact and have low pressure drops. They are ideal for many applications for fan intakes and discharges, engine air intakes, small steam vents and centrifugal compressor inlets where absorption of high frequency noise is important. An FPE, FPCE, FPSE installed in series with an M-line chamber type silencer, can provide 10-20 enhancement of the overall dBA silenced exhaust noise of a reciprocating engine. Addition of an absorptive design silencer may improve the overall attenuation of the system by 10 to 20 dBA.

SILENCER MODELFP / FPEStraight through, absorptive silencer design with no center panel for low pressure drop service. Expected attenuation is 20 dBA.FPC / FPCESimilar to the FPE but with an internal center panel which displaces part of the nominal flow area. Pressure drop is higher but the FPC is more compact in diameter, length and weight. Available in sizes 14″ and up, the FPC is excellent for engine and compressor intakes and fan intakes and discharges. Expected attenuation is 20 to 25 dBA.FPS / FPSEDesigned with a center panel, the FPS / FPSE body diameter is enlarged to enable an annular flow passage equal to the full nominal flow area. Pressure drop is intermediate between the FP and FPC models. Expected attenuation is 15 to 30 dBA. 


Designed to ASME Code, MAXIM offers the models ILL and ILM to reduce the noise generated by valves and compressors. Typical noise reductions associated with high pressure applications is within the range of 15 dBA to 30 dBA.


Highly efficient in acoustic design, the MB series is used to reduce the noise radiating from blower piping or blower opening. Typical applications are for rotary positive blower intake and discharge, vacuum pump intake and discharge, and centrifugal blower intake and discharge.

SILENCER MODELMB11With its straight through acoustically packed design the MB11 offers good silencing for many blower applications. Typical attenuation is 15 to 30 dBA.MB21An efficient economical design, the MB21 is useful for blower noise reduction in applications where some background noise is always present and high degree silencing is not required. Typical attenuation is about 24 dBA.MB31A superior design, the MB31 incorporates an acoustically packed connection with a chamber type design to offer a high degree of attenuation of blower intake or discharge noise. Typical attenuation is about 30 dBA.
