I was just wondering if it would be worth the 1000+ or so I'd have to spend on headers, high flow cats, etc. How much of a horsepower/torque gain should I expect since I have a Saleen S/C? I've heard you get more of a gain if you have forced induction.

Ive read around 30-40. The sound would be worth it though.

The sound is definitely worth it. I dunno about 30-40 hp. Seems a little much. I'm putting 315 to the wheels N/A with the mods in my sig.

315 is really good for those mods. Nice.

Thank you. The aluminum DS and flywheel(just added) really help indecreasing the drivetrain loss. Plus the intake I have is friggin ridonculous.

I'd say more like 10-20 is at mot the biggest gains you'll get unless you are above 12psi or you get you get a CNC job...or a stroked engine...

Man I have been told that you should only buy long tube headers if you do have a supercharger, so go for it.
