Product ReviewsTwo Brothers Racing - 005-4070105-S1 - S1-R Full System, Carbon Fiber Muffler

Very Awesome!

This exhaust sounds and looks great.
Easy to install. I picked this exhaust for a couple reasons. I like how it fits tight to the bike, it doesn't stick out very far.
The price was the best I could find, and of course, the sound. It really brings the bike to life
After riding the bike for a few weeks, I decided to get the EJK fuel kit. (To much backfiring)
I know the backfires wont hurt the bike, But they are annoying.
The two brothers exhaust and the EJK fuel kit is a great combination! My bike sounds and runs amazing!Read full review...
