Really decreases the sound - by 1/2 minimum - and doesn't change the power of the engine. A really good thing to have with the expansion chamber.

muffles the expansion chamber sound .. its great but not 100% i wished it was more a flush fitment then it would be A+ for looks after painted

This is a cool little muffler, My bike was very loud but I thought a muffler might affect the power increase that my expansion chamber gives Me. Well not only does this muffler soften the exhaust noise it doesn't affect the power at all!

Good small size. It doesn't cut down on the 2 stroke sound as I would like. Also, use some muffler/exhaust pipe sealant on the expansion chamber end, before u put this on otherwise it leaks.

installation is a lil bit of a hassel as i had 2 drill a hole to mount it but over all a good piece of equipment

this muffler is easy to install, does just what they say, muffles the sharp 2 stroke tones. Does'nt quiet it down as
much as I would like.
