Posting again to get my 'quota' in so that I can start using the forums without restriction. Looking forward to getting my full arrow exhaust fitted but I bought it off a guy who had it on an '07(mine is an '09') and the flanges that fit over the manifold studs are a couple mm's narrower centre to centre than my stock and won't slide over the studs. I thought they were all exactly the same??!! I tried to just fit the arrow as a slip-on instead but that was leaving the can WAY too close to the tire for my liking. Am thinking of going to a custom exhaust shop for some help. Guess I don't have too much to lose by trying to drill out the holes a little bigger? Advice? Any other must have mods? I'm happy with the windshield I'm running and have shorty levers, aftermarket mirrors, and a givi topcase but otherwise am stock. Opinions on power commander in conjunction with the arrow exhaust?
