Well, Bob found a guy who can weld stainless using stainless rods, and Bob can cut it naturally. I have a feeling they're going to try to do what I had suggested earlier.

I have a better way that nobody here or on clubgp seem to have thought of yet.
A member on w-body.com, Miko K, decided to post in my thread. He built that twincharged L67 cutlass supreme coupe with a turbo the size of your head, an Eaton M112, and what appears to be an intercooler. He used SLP headers, and here'* what he had to say:
"Back in the day, I had a welding shop heat up the rear SLP header and bend it down so it would clear the body of the car. Then I shortened the downpipe and moved the flexpipe after the bend. Worked good on the GEN1 Cutlass:"

$205 shipped for the headers, no cost to bend them, labor charge for Bob'* co-worker to re-weld the downpipe bend before the flexpipe, and I'm done. Sorry to say, but that sounds like a hell of a lot easier way to do things than butchering the firewall.

i guess one of the other roberts suggested it a few posts before me actually...
and then a different robert replied
then i replied...
94GPGTP: heat all the header pipes and bend them all at once to form to the way you need it to fit.. ghetto.. yes.. will it work... maybe... will you try it... no... just a thought out loud..
Bob: Great, except I have nothign to bend them with, let alone have them retain their tubular shape.
RobertISaar: retaining the shape: sand. pack the tubes full of it and they won't crimp....
and i guess it was page 46 of (now) 55....how that thread got so long so quickly is a mystery to me...

More from the guy who made his headers fit, for future reference:
We C-clamped the rear header flange to a work bench and heated all 3 primary pipes, close to the flange, then bent the rear header so the merge pipe (where the flex piece used to be) moved down (as towards the transmission and away from the firewall) about 1.5". This gave it enough direction and the rest of the welding made it work perfect, without doing anything to the firewall. Later i stuck the crossover pipe into the rear header, tightened the clamp and heated the short pipe that sticks out of the rear header(for the crossover) in the reverse direction, so the crossover pipe is pointing where it'* supposed to.
