6 Months Later and Still Love it

Had the SBP exhaust for 3 or 4 years. Loved it but needed to quiet things down a bit. This got rid of the high pitch noise and made the engine sound more mature. Repainted exhaust + silencer gloss black and it looks great!

It does lower alot of the nasty noise by simply using hose to attach to back of my pipe,it also knocked down some maybe a slight amount of top end but it satisfied my ears and prob some niehborhoods on a full throttle fly-by,it comes off simple too,so to easily be able to install and remove noise reducer is a very good thing around here,i like it and im sure my immediate neighbors do too.The hard cores like the expansion pipe open and screaming.

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.
