How can you have a catted off road pipe?
Anyways, you'll fail visual in California with any aftermarket mid pipe. Catted or not. You need the stock one to pass.
Check your exhaust pipe to see if you see a tire mark on the exhaust.
It'll look like what I have on mine.
You could try to adjust the cat back or get 1/4 or smaller wheel spacers. I would try to adjust the cat back first. I have the same problem as you.
When I hit a bump my exhaust pipe hits my tire. I might have to go with a 3/16 or a 1/4 in wheel spacer if I can't move my exhaust out of the way. I have heard horror stories of wheels falling off and things. Should I worry if I had to use a wheel spacer.
Anytime you lower a car the ride quality will never be the same. The springs and shocks/struts you went with are for performance. You went with performance over comfort. Those 18 in wheels don't help either. Your just gonna have to deal with the ride being bumpy. Get used to it or go with a...
