OK, I am tired of cracking my header so I think the cast manifolds are the way to go. I am planning on swapping intake manifolds also and a mustang tb (if I can figure out how to adapt it to the renix). This is on a 4.6L stroker with ported and polished HO head, and a comp 250h cam. I will be replacing a '94 HO intake and exhaust and tb. What kind of gains should I expect out of the new manifolds. I know Jeep claims they produce a better exhaust note so that should be a plus.
