I am getting ready to do a new exhaust system plus intake mods. As I will be adding Corsa cat backs plus a hi flow cat; I am up in the air about whether belenger headers will give me enough of an HP increase to be worth the cost and time over the factory header. Any advice?

It depends on if you wish to do more work after the headers. Hi flow cats and headers netted me about 12 to 18 rwhp on the dyno. Since you have the 708 cam on your car it will net you about 10 more hp.

If you plan to have the heads ported, rockers and cam then definately do the headers. I did notice a SOTP difference.

Is that 10 more over the 12 you got?

Is that 10 more over the 12 you got?

thnk he is saying he should get a total of 22-28 RWHP due to the fact he has the good cam, but I would bet the pick up will be closer to 40 RWHP.
