BTW, what size are the primaries on those headers? Been reading up on headers and the results between different size primaries, and I'm rethinking my idea of "upgrading" my 1 3/4" inch primaries to larger ones. For the sake of low end torque, I just may be better off sticking with what I've got now.
But was curious if this install went to large primaries (1 7/8" or 2"), and if so how that affected the performance of the car.
