They ARE called 'donuts'. Thry may or may not work on a Pantera. With Hall
mufflers, my welded Hall brackets applied force to donut-gaskets such that
they would crack within 50 miles or so. With donut gaskets, you really cannot
tighten the flanges tight- the thick donuts prevent it- so vibration & heat
tends to pound the fiberous donuts apart. A better system might be the
steel dome/socket connecters that do not use gaskets at all but do allow a
little articulation for misalignment. I personally use flat gaskets on the
header-to-exhaust pipe connections with steel centers to resist burn-out. Good
luck- J Deryke
