Okay I am looking at a header that is a tork step header they make one for a b18 and 1 for a b17 and one that is for the b18c and b16a. now I know all will bolt on and the only diff is the pipe size. one : 1-1/2 in the other is 1-3/8 inches at the cylinder going down to a collector of course which would give better results?
Any help would be greatly appreciated..........
I am running of course a b16
