Default Re: Predator 670cc muffler options

Any muffler that drastically reduces sound will also kill performance. There is a happy medium there. I use a generator muffler made for semi truck generators. Google "Thermo King muffler". They are usually 500cc+ diesel engines on those gen sets and the mufflers they use need to be quiet enough to allow noise at the truck stops to be low. I use one on my cart and I also use a silencer insert that I found on ebay. It's pretty quiet, like a stock atv.
