Thread: Headers/Exhaust....point me in the right direction

Orrrr ya could just pick up the parts you need to connect it .....ahead of time.

The headers you have in your hand, so finding out if it's 3inch OD or ID is really easy. You likely can't find a reducer to the stock 2.25inch size pipe from a 3". Some exhaust shops will make one for you super cheap. But that's a large difference. Another idea is to get two adapters. From 3 to 2.5, then 2.5 to 2.25. A couple of clamps and some planning and it'll be fine until you get a different catback or have more work done.

One of the three installs the other week had this issue. An extra 30 min of parts hunting and it was cleared up.

That works. Keep in mind that dropping the back of the subframe allows you to wiggle the rear header into place. Get it held on and then lift the subframe, mark where the O2 will hit on the tunnel edge. Pull the header back out and make the firewall/tunnel edge move and put the header on for good.

Coming from the Bonneville world is nice because nothing was made for that car. There's no catback flanges to bolt up to.. it's all make your own, think outside of the perfect situation box and come up with solutions.

When someone says can't, my mind starts to think and look at the problem. There's an answer for every question, the challenge is finding it.
