Luke, I'm planning to cut up a set of off-the-shelf 930 turbo headers so I can fit a T4 turbo to it, so that's the reason why I want a 2->1 merge collector with T4 flange to replace the T3 one on the 930 headers.

There is no way in hell I'm paying USD$2k for all new merge collectors. I'd rather have a custom set of 1 5/8" headers built locally for that price

I understand can also try Woolf Aircraft. Woolf actually supplies Burns with all their material, and produces off the shelf collectors too. ALOT cheaper than Burns.

I've tig'd up headers before to accept T4 turbine flanges. Nothing as fancy as Burns, but get the job done efficiently. I should have made a jig for that setup. Shouldda wouldda couldda as they say If you're handy with a tig, or even mig, it's actually not all that hard to do yourself. I believe Woolf even sells pre-swagged mandrels so that you can make a factory slip joint style collector that will seal positive and expand with head so it doesn't stress and crack over the thermal cycles Fun stuff...
