yeah im gonna go wiht the yoshmiura full system..its really nice carbon fiber and it comes with a factory approved Spark Arrestor and 96 decibal reading with the insert..but when i want noise ill take it out and have all the power.

 

Have you heard of the Pulse Charger? in my opinion it is the best 4-stroke exhaust you can buy. but it will run you about $700. thats what i got on mine. the pulse charger is the only exhaust i will ever buy.
