Exh manifolds in an Early A...

Sorry, my point was that no matter how much flow the larger pipe gives you the smaller 1 5/8" pipe will restrict (control the flow) in the end. What I'm trying to say is that you could put a 4" pipe behind the manifolds and it won't make much difference because the manifolds are the biggest restriction in the exhaust system. I know you have to do what you have to do, just trying to help with info. treblig

Ahh, sure man, no problem I understand now. You are 100% correct. I wasn't trying to argue, just "understand". The 2.5" pipe wasn't to get more performance at this point, just get gasses from the front of the car to the back of the car. it was a relatively cheap setup that came with almost everything we needed minus the header-flange to exhust-flange portion. At some point when he decides to install headers, if he can afford them, he'll be all set.

I appreciate the comments man, I'm always learning. (or trying to).
