I'm looking into sourcing headers and was wondering if anybody knows of any dyno tests that may have been done from what is out there. Dc sports claims 18-20 hp just with headers (not sure if that's to the wheel or fly wheel hp), Rm claims 18.8 hp to the wheels coupled with their muffler, comptech doesn't mention anything at all. I guess overall peak hp is important but I'd like to see the entire picture with hp gains throughout. Does anybody have any good info or advise on these different headers or any other headers available?
