Looking for opinions before I purchase headers , I've had my eye on tsp's new 2" primary 3.5" collector. Since this motor is in a truck there will need to be some modifications, I know speed engineering sells a 1 7/8" stainless header that will bolt right in. My question , is it worth the extra primary and hp for the extra money and work .

for your application, absolutely. with that motor, on motor, it would be worth it. Add your spray into it and it is a no-brainer.

Guess I'll go with the tsp's then they seem to be a quality piece for a good price

Do you have a link to the write up Zmg00camaross I'm gonna have to modify something because there going into a RCSB truck I know people have used there 1 7/8 headers on trucks but I doubt these will squeeze in there but nobody makes 2" headers for trucks
