Check out the OBX headers on ebay! Full stainless bolt on system.I just got a new set from a member on SSS.com cant wait to install them on my SS. Hopefully they go on with no probs.

 

I have pacesetter on my LQ4, look through my post to find the thread I made with pics. Sicne you have a 6.0L, you can't use the ORY pipe, as the 6.0Ls have a true dual kind of setup. You will need to fab up pipes from the collectors to the exhaust.
