I know there is a doghnut of some sort from a cadillac that can be used to install this and prevent leaks. Does anyone know off-hand the part nu,mber at any parts store, or at least what type of car its from? also, any general tips on installing this along with a ported elbow
TIA
 
Hey, I have that pipe! Slightly modified for fit, though. I didn't use any gasket, just a thin bead of high-temp silicone around the head flange. I did use allen-head bolts instead of the hex-heads for increased clearance, and a 4" wide SS band clamp at the swedge.
 
No gasket here either. Just a lot of Permatex Muffler and Tailpipe sealant. :)
