Pacesetter Headers
Also, is it a must to get the LT4 knock module now that I have headers? Took it down the road after I got the headers on and it seemed to run kinda pitiful actually. Gotta get my duals and bullet mufflers put on this week if I get this collector problem straightened out.
Your car wasn't wrecked in the past was it?? With headers it only takes a small tweak in the structure to make things not fit well.
