I have a 99 400ex with a K&N, DynoJet kit, and now I want a pipe(but not too loud). I was leaning toward the Big Gun. I read that it increases the lower to mid range. My question is did anyone notice a loss in the top range? I want a little more grunt(for the woods) but I don't want to lose any top end. Any other pipes to recomend? Thanks.

 

you should check out the supertrapp isd2......its adjustable and not a loud as some. later
