Thanks-the headers I got for you were awesome, now to drive the car and see how they perform!! Initial startup to check for leaks went well-barely more noticeable from a cold start, but much more noticeable once the valves are open.
At a cold start-there really is not much of a difference (if anything with the race header I would say its more "grainy" at idle and revs if thats a good word to describe it. On the street there is a noticeable difference in sound-almost cup car like with the valves open! Valves closed, its barely louder than stock IMO.
