Headers
That's covered in this sticky
Exhaust Mod Guide
There seem to be five primary considerations. All of the headers with in the same primary size group dyno about the same, so swapping between one producer's 1 3/4" header and another won't net you anything.
SLP is the worst fitting, if you are lowered that matters a lot. Stainless or coated headers will last longer and look better, but cost more. TSP, Pacesetters, Speed Engineering all make good headers. Kooks and ARH are probably top of the shelf, but expensive.

- Primary size
- fitment
- cost
- material
- longevity (rusting out, cracking)

SLP’s first design had **** fitment, they redesigned them in 04 or 05 I think and fit better now. Speed Engineering is garbage. TSP and Pacesetter are good and ARH are the best.

Since when are speed engineering headers garbage? I have the 1 7/8 and they fit perfect.

TSP ceramic coated 1-7/8" headers have a good reputation for fitment and are priced very well. They're a good choice for either a bone stock LS to a 600+hp LS.
When I bought my car it had SLP headers,it performed well. I was at stock height and the headers would hit on ANY speed bump. I took them off and put Speed Engineering 1-7/8 headers on with their Y pipe.Much better clearance .Now im lowered and only hit if I go over the speed bumps to fast. I just cant spend a grand on "kooks" headers. Do the give more power??? not per dollar.
