For a project I'm doing, I will be swapping in a 351w based stroker. I just bought some headers for a fox body, but they will fit an sn95 5 spd also. They are RCI 1 7/8 primaries with 3.5 collectors. My question is, what type of midpipe will bolt to these and fit my car? Will a MAC prochamber for a fox bolt up? Also what size exhaust should I look at running back from the headers? 3.5? 3?

The project is a 500-600 hp N/A 408 stroker. Anyways....let me know. THanks.

Anyone know??? Thanks.

not many people here are running things like that, so its hard to say

but i do know that i have never seen a h-pipe made for headers that big. take it to a custom exhaust shop, they'll be done in under an hour.

Thanks for the advice man. Hmmm any idea on how much a custom exhaust would cost?? Let me know.

3 or 3.5" please....a 2.5" is all you need your not going to find 3.5" mandrel bent pipeand you will pay out the *** for 3" mandrel piping.....does one of the headers have a tube in it the right one it must be plugged.....seems you were being cheap and bought a race header with a 3.5" collector which will rake on any speed bump plus it's useless in being you'll need a reducer to fit an exhaust that will work thus crating back pressure which your trying to get rid of...try doing a lil homework!
