Automotive muffler for maxiv

[Tomo]

hi
99% mower mufflers donot have any sound absorbing material . Quality sound absorbing material used by oem can be expensive if available
Very thin single layer steel casing material -transmits noise easily
There physical size is small --reducing sound absorbtion capalbilities
99 mower mufflers are an exhaust redirection device
twin and triple noise dampening chambers as per auto industry mufflers do not exist on mowers etc

An 1 1/2 inlet/outlet triple pass auto muffler sounds ideal
Intake noise and cooling fan noise will still exist
Fit noise reducing products to engine cover

A heavy wall /barrier is highly recommended to help noise reduction . A light weight barrier vibrates therefore transmiting noise .

Noise pollution is hard to remove and requires a multi situation approach .Sound studio construction and generator noise reduction is a prime example of this subjet and how challenging it can be .

Agreed. I may have to build a "suppressor" muffler for my max. I hope the ATF doesnt want me to register it and fill out a form 4 for a tax stamp
Just making a joke government guys

I sent off information letters to two lexan plastic companies last night, looking for opinions on their products for my floor project. Hope to hear back from them soon

HI,
The easiest solution would be to use that dynomat stuck to the underside of the original floor pan.
Overlap the edges and if required use aluminum plate as trimming to take up gaps etc
The benefits would include
cost effective
easy install
the total weight would be greater than another style of plastic---------- weight = sound absorbtion
APPLY 2 LAYERS IF NEEDED
The alloy sheet side is oil proof -easy to clean

Has anyone tried the add-on mufflers that being sold for four wheelers?

Do you have a link to share?

This would certainly be the most cost effective, however it eleminates the main goal that i want to attain with this transformation. The ability to visually see whats going on in real time down below my feet is something i feel is important. We know parts fail on these machines, most often due to lack of maintaniance. IMHO, two things happen if one can see through the floor; a) it helps remind us that we should check the moving parts more often, b) it allows a person to see when the chains get "dry" and need attention. I really like the idea of being able to have "spray holes" drilled through the see through floor. This will allow me more control over knowing the chains have been well greased. If i find out that the clear floor is too much cost or hassle, i may go to the effort to have a built in "oiler" lines that are positioned to oil the chains. It would not take that much effort to have a small electrical pressurized unit that is switch/push button activated on the dash. This would again give me the ability to oil the chains without jacking up the machine. If i choose to go this route i'll still look into some sort of lexan slotted window in the floor so i can visually verify that everything is getting oiled. I know this stuff is a tinkerers way of doing things, but thats what i am. I like to tinker and make things easier when ever i can. Talking about it here kinda gives me an outlet and a place to express ideas that someone (hopefully) may point out will flop, or say wow thats a cool idea that has a place in our hobby and can be of use.

maybe there talking about this....

Stealth Exhaust - Kolpin Powersports

[Tomo]

hi
rcn11thacr
Did not realize u r such a tinkerer and the clear floor is such a high priority .
I was taking the practical route .[FYI removing floors to grease/lube either every trip or every second is a good idea ,allows u to check chain tension and inspect tensioners . U need to roll or jack up one end of 6x6 to get the slack side of chain to happen, then check amount of slack ]
By jacking and checking tension every second or third ride also allows u to check sprocket to keyway slop [freeplay] or if using sprocket tube drive bolts for shearing or excessive wear in bolt,axle tube .

An attachment so small typical only achieves noise reduction by being restrictive . A large enough outer body size of a muffler will have a large amount of sound absorbing material, this is the key factor.

Before every real ride I take a min and remove floor, check and lube chains ECT.... It's soooo easy for piece of mind... Norm

[akcrawler]

The Kolpin stealth exhaust was exactly what I was thinking. I understand what you are saying, tomo. I am sure it would not be as good as a full-blown automotive muffler, but it should help a little. It is supposed to cause very little backpressure. I have not seen one in person and have not dug into it enough to go find a cut-away drawing to see how it works.

I was just wondering if anyone had tried it.

An old thread but to share an idea, If you want to see the chains you simply could add lexan windows to the existing floor. I think they would get too dirty rather quickly to see though but if you want to see through the floor...


I am more interested in the muffler/quiet it down aspect.

[rcn11thacr]

Well, since you brought it up... thats what i did during the interim. I used the lexan and added it to my floor. As for the muffler, i havent done anything with it so far. I got side tracked with a golf cart build. ezgo with a 300 suzuki 4x4 drivetrain with the factory hi, low, and "super" low gear . been busy workin on that for awhile

Yes, i like to tinker...

[Noel Woods]

I like the little UTVs / golf cars as well. Post up a pic of what you have.

Perhaps a golf cart thread I'm game

Nothing more quiet than a 4 cycle EZGO golf cart muffler, pricey but handles 18hp just fine. the EZGO workhorse came from the factory with a 16hp Vanguard.
