How do i mount a lawnmower muffler on my stock?

[Xiodinc]

I want to get a lawnmower muffler on my stock muffler to further quiet it. i was wondering how you mount it.

Most folks weld it on. Some try to use a piece of hi-temp rubber tubing and a couple of hose clamps. If you go the hose and clamp way you will need to support the lawnmower muffler, or else it will eventually fall out of the hose or the hose will break.

You should be able to braze it on with a MAP gas torch as well, but use care. The muffler I purchased was galvanized, the plating will release arsenic when heated! Be sure to either remove the plating or work with extremely good ventilation (outside?). A machined adaptor or bushing will aid in keeping things lined up while fabricating if you have that option.

Weld one half of a pipe coupling on the stock muffler end so that you can screw a cigar shaped mower muff on- that way you can clean it or replace it as needed.
They come in 1/2 inch or 3/4 inch sizes, work well, and are cheap.

so do these mufflers actually keep noise down? and do they alter peformance?

Thats not me up there!?!? I would have said to use Jb-weld lol on it.

 

[bairdco]

it's just a stupid gimmick. if you type "you" in brackets, it changes the user name to whoever's viewing it.

Lol had me there for a second.

So, again, does this noticeably reduce sound and what effect on performance?

My experience is the more mufflers -the quieter, the longer the whole exaust system is the quieter it is.
As for loss of performance, I don't know about motorbikes, in cars, if the muffs are big enough there is no or minimal loss. Works great on small tractors too.
