Ok, i just got the 80 series on yesturday, and it is barley touching the heat shield on the back part, with plenty of clearence on the top. But around 1800+ RPMS it seems to vibrate the car, no i don't mind this, im just wondering if its normal. its pretty loud, but around 3500+ its no louder then my previous exhaust. and i'll post some pics later today cause i have a few more questions about stuff.

wow, it shakes the car, that's awesome. I had one on my '85, I'm not sure if it shook the car though. Of course, everything else was stock.
