Hey man nice to see you over here…
Well given you haven’t heard much the last few years should be good evidence… IMO on a stage II car and based on what I’ve seen, read, and experienced they don’t do much if anything, neither do the hfc’s or test pipes… Don’t think they hurt either and you do get some weight reduction. I feel the small variance in ET and trap between the various setups, IE headers, test pipes, hfc’s, and stock shows this along with my personal experience at the strip with two different header cars, same headers though… literally… lol I could care less with what any vendors dyno shows especially when they’re the ones selling said part.
I still don’t think they’ll do much on a stage III car either and EC’s claims are down right fabrication IMO…
If someone is staying stage II, they should try to get a few other things for performance way before these headers. First thing I’d want and I’ve been trying with various company’s for a few years is the larger TB and intake. Now I don’t know if the one that is being used for stage III would mate right to our current setup but I’d suspect it does or could be modified to do so… You’d need APR or GIAC, etc to write a tune though, my guess is they’ll explore this anyway but that’s a guess… It’s really a no brainer on PD blower cars. I’d also run a larger crank pulley for more boost especially if you can couple it with the above… Finally, someone really needs to run a small shot on this car as I think it would be safe as long as you don’t get carried away.
