basically I didn't attempt top use the modified single outlet manifolds (X5? see garagistic site for ref.) . so Ive no idea if they would pass BAR.
I wanted a 'stk' configuration 4>2 /2>1
at heads : cut off flange end of stk header leaving as much 2bl wall header as possible to fab onto. used SS pipe
reused stk 2 bolt flanges at ends, 'headers' end next to blk/trans joint. Stacked, not side by side. pointing down at 45*+- . this is tight but workable.
Reused the stk 2>1 connector/pipe w/ reshaped pipe to end of headers.
Then 21/2" back to Calif legal 540 walker cats w/ O2 sensors. dual 21/2" cat back to muffler.
The BAR ref commented the headers had been modified but were representative/ close enough to what his diagrams showed.
Your results may vary.
I probably paid more for the exhaust system then all the rest of the swap.

I'll be swapping the motor for an "upgraded" m60 in the next month or two... hopefully can take some pictures when the motor is out.

headers
So just to confirm. The only thing you left stock on your exhaust was the flanges?
The referee was ok with using all new exhaust piping?
Did you need to follow any guidelines like runner length and size, collector and cat location etc..?
Does it look close to the stock header design?
What can make the headers fail inspection?
Thanks for the info I'm in San Jose doing a s62 swap, trying to figure if i should custom fabricate or cut/bend/rotate my stock headers.
