daver

its a '90 teg, but actually a b20 now. I have a line on a '93 gsr header and i'm wondering if it will have worthwhile power gains. I realize that i will have to extend the down pipe to reach the cat and also extend the O2 wires...

and I know its still a "stock" header, but i've heard that the '90/91 teg exhaust manifolds flowed like crap compared to the others (and a 16.4 may proove it).

thanks,
