sidepipe clearance needed

200 Views 5 Replies 3 Participants Last post by  EddieAshleman
I know this has gone over before but I cannot seem to find the link.

What is the minimum clearance I shouls have between the sidepipes and the body?

I have 4 into 4 headers on a 302.

factory cut-outs

The driver side exhaust is about 1" high and1/2" too far back.

I am about to cut them larger, I just want to know how much?

And is this normal to be off by this amount?

Thanks for any input!

I found a "windfall" concerning sidepipe installation when I used another's advise on inserting Car Chemistry Inserts into the J-pipes. The CC's wouldn't slide in due the conflicts with the flange on the J's. I used a power band saw to cut the J's in half. I used a Pep Boys 2.5" exhaust pipe union to put the two J's back together. I only torch welded one end to one half of the J's til I got the pipes lined up. Then I tack welded the union to the other J, took it back apart and finished the welding. The exhaust pipe union set-up let me twist the J's and attached side pipes as much as needed to make them level, etc. I found this a bit more accurate and easy that ovaling out the flange bolt holes (in my opinion).
