When I had my Tanabe first installed (at the time I still had my stock rear bumper) it was about a half inch away from touching it. But if the exhaust would shake, it would hit it. Installing a rear lip was out of the question for fear that it would melt it because I know that it was gonna touch. Luckily the rear bumper that I have now (buddy club rear bumper) was a little more forgiving and it gave a little extra room between the tip and the bumper itself.
