Default Oval tubing

Bryan,
We cut the flanges off my collectors (3 1/2") and then welded
a short piece of round.. then opened up a piece of 3" so that
it slips on.. my whole exhaust comes off in one piece... it goes
under the rear end... a couple of bolts welded to each side and
it holds it together

I do not have Tri-Y headers (not made for oval pontiac heads)
so they do hang down a bit but my bellhousing is actually the
lowest point.. need to square that off next time the motor is out
(frequently on this car 12 times now)

My subfame connectors are also very low so I raised the car
slilghtly from 1 1/2" clearance to 2 1/4" clear.. really tight but
not too bad on the streets now

They make a spin type fitting that is fairly small and ss
that you can use. one of the Pantera Race cars has them
as we change from straight pipes, to two different types of
mufflers depending on where we run...My Ford truck actually has
these

Good luck and have fun running the car.. I am taking mine out
for some more test runs to see if the pushrods will stay in the
motor this weekend
