My neighbor gave me his slash cut pipes off his '05' and I took 2 of the 4 baffles out. YES 4 are in there. Anyway, it sounds great. Not too loud, nice thump. Having said all that, I don't think taking just 2 baffles out should make a hairs difference in jetting. I know their pretty lean from the factory, but I can't believe that they are THAT fine tuned. OK, so I'm going to call my dealer tomorrow and make sure. Will keep you informed. BTW, runs great too!!!
