Hey, I was thinking about getting a K&N Filter, Aftermarket Pipe, and the 500cc kit High Lifter has. Does anyone have the FMF MegaMax 2, White Brothers E Series, or the Supertrapp pipe? what one has more power, and what's the loudest (No neighbors to bother, hehe.)Thanks alot, and if anyone has mods similar to these, tell me how it does, thanks!
