Did you happen to dyno your car azcamber? Any realistic idea on hp / tq gain? Looks really nice! I thought 20 HP was what was quoted by others. On my old Mustang GT with a JLT 2 CAI, SCT 2 Evo tune, LT Kooks headers, X-pipe, High-flow cats, and Borla S-type equaled 82 HP. But not being able to tune a LS430 is a major downfall.
My 2001 was the car they prototyped the headers on. At that time everything else was stock and it did bump it 20 up at the wheels. Those dyno graphs on the Ls430 headers are legit.
That being said I have them on an 06 now which means i have one more gear in the trans, and a different rear end ratio. Keeping in mind with the cat back exhaust , which helps out tremendously, and an intake which also helped tremendously this is a completely different animal than the almost stock 01.
It surprises a lot of cars on the street if you know what I mean.
I would love to have my car dyno'd now and see what it puts down but I have had other priorities.
