KMT he wants to get this 90 to 300rwhp. His exhaust from the collectors back has been quoted and is custom
2.5 down pipe, 2,5 cats, Magnaflow res 2.x2.5 in and 2x2.5 out, 2 x2.5 around the tank to Magnaflow offsets that are 2.5 in.
He is doing exhaust first, not Dave's suggestion of doing yhe intake and injectors first. Me I would follow Dave, him he has other thoughts but who am I to suggest anymore than I have.
I can't see those mustang type header from SpinningWheels doing much except they LOOK like all the collector pipes seem to be the same size, not hammered flat in areas like the stock manifolds. Just have no specs on them and I can't seem to get hold of Diane.
The Mustang Mac shorties seem to flow well but you have to modify them to clear the steering column, I did see pics of that in the forums.
Thanks
