Congrats on the new bike and welcome to the site! Go ahead and lube up the hinges on your wallet, you'll find plenty of ideas on here that will have you opening it frequently. As Steve mentioned, the Fullsac set-up is a proven system and a lot of us use it, myself included. I have the DX pipes and 2" cores with TTS, had Doc at Doc's Performance tune it on the dyno, runs great even with the stock cam, plenty of torque where you need it most. You can find some sound clips on here or probably easier on YouTube, actually I think Fullsac has some on their website; most fail to impress like the real thing though. Good luck!
