I'm seriously studying the Staintune exhaust option for my R III.
1) very close to stock look with the three mufflers,
2) very well designed 1 into 3 collector to replace the cat box,
3) awesome gain : 22 hp & 22 f/Lbs at the rear wheel claimed,
4) very interesting removable sound restrictor that drop the noise from 98 Dcb to 93 Dcb (very close to stock noise).
Is there some people here that knows Staintune factory ? What is your opinion about that setup ?
