Dont worry about a MAF, either a K&N FIPK2 (which I have and love) or your standard aftermarket lid w/a K&N filter and possibly a FTRA will get you more power. I have Pacesetter headers, off-road Y and a Dynomax bullet muffler dumped before the rear axle and it sounds great! Its not raspy like a Loudmouth and has a great tone. Check out ls1sounds.com to listen to different exhausts in action.
