Just be careful with the shorty headers... I just finished installing BBK shorty's and my mac prochamber pipe was hitting the floorboard and would tap when the motor would torque... I got one of my special tools and fixed it... (the 3lb hammer) Beat the life out of the floorboard... It doesn't hit anymore... It sounds bananas with a midpipe/slp exhaust... But it had a lot of backfiring sound... When I did the headers it made it sound cleaner... (P.S. what a cu** of a job)
