im going to switch to long tubes and dual cutouts, how much of a power increase should i expect from as&m headers/ORP/open borla?? see sig for mods

 

Honestly, I've asked this question very recently and the concensus seems to be that there's not much of a gain in switching from ASM's to LT's. Maybe a little up top, but that's probably it. ASM's have been proven to easily support 750 hp.

 

thanks, i may put my money towards something else.

 

Yeah, I'd wait on it. I decided the same thing too, just keep the ASM's.
