Ok yall, don't beat me up to bad with this. I have Scorpion slip on's on my 03 RC. It sounds good but its not as aggressive sounding as I would like it to be. I love LOUD > The louder the better for me plus people around here drive like morons! With that being said I was thinking about having a custom shorty exhaust installed by the best custom motorcycle shop in the county. While having the exhaust done I was also having it re-mapped, re-tuned and dynode. It does have the PCIII and the speedo healer. I'm not sure if that would be a big mistake or it could work if done properly and correctly. Any info on this would be cool. Thanx!
