I love it! The sound is a little louder but way cooler! Its like "Barley Awake" said "Its like a pissed off dirt bike" It just gave my bike that little kicker it needed! Its more responsive! I think its the best add on I've run across! I ordered it on monday and received it on friday! SWEEEEEEEET!!!!!!!!!!!!
also here is a little twist to the chain tensioner. it works great!
