The quality looks amazing. The fit to engine is probably is perfect as well but to the stock cutouts looks a bit off. How much below the lowest part of the engine does the can hang? My car is body lifted as well so the tighter to the body the better. Is there packing inside for sound dampening or just tuned pipe lenths? I know... too many questions. Where to purchase?
Oh, I should have noted a few things:
1) Ignore the fit to body. I'm running a 901 Porsche Transmission with custom motor/trans mounts that I fabricated myself. Motor doesn't sit in the factory location.
2) I've also got a removable apron, the alignment of which moves somewhat when I pull it off/put it on.
3) I use thicker gaskets which push the muffler down a good 1/4"+
As for your questions...
a) Bottom of muffler body is not much lower than bottom of heater boxes...


b) no packing inside. I've cut and welded mine to clear the drysump pump, definitely no packing.
c) AVR - Usually in stock.
