I ordered some Hooker ceramic coated LT headers today. It cost me $695 for the headers and $135 for the matching o/r x-pipe. I made an appointment to have them installed in two weeks for $800. The shop will then dyno-tune my car using my Diablo Predator. With my current mods, I am hoping for 270 rwhp. Is this realistic? I will be sure to post the results when I get my car back. The shop that I am using also grinds its own custom camshafts for $595. Unfortunately, that will need to wait until next summer. I will also probably have the heads polished and ported at that time.
