Jeep manifolds? I don't think that Jeep manifolds will fit a sbm. And the only Jeep that I know of that has a mopar V/8 is the 4.7 and from what I've read those won't work on a sbm either. If I'm wrong here and I very well could be, what year Jeep manifolds fit a sbm? And do both manifolds fit? The whole idea of this post is what if any truck exhaust manifolds or car for that matter flow the best, this idea was for a budget exhaust system that would help over all performance and not break the bank account. I've seen Doug's headers on a dart sport but they are like $900. If I can get the duster that I'm going to look at it already has headers, the other one doesn't have headers and I was just looking for some better flowing exhaust manifolds. What would be good mufflers to run?
