Ok...so after being a tad skeptical about ripping into the exhaust system of a brand new 2008 R1 with just shy of 400 miles on it, I finally brought myself to do so with the installation of A&R Motorsports race baffle kit. Honestly, I'm a pretty straight forward person and usually tell it like it is and this kit deserves every bit of praise. Anyone with a little bit of technical know-how and the right tools can do it. Everything is provided with the kit. Rivets, packing, baffles, etc... The end result is everything that they had claimed it would be. More power, more torque. (Though I DID install a K&N Filter at the very same time. So with this in mind, anyone who doesn't wanna give up their stock exhaust appearance and doesnt have/want to drop 1200 bucks on slip-on canisters, I would highly recommend the R1 Race baffle kit from A&R Motorsports. :rock
