Header, Intake, & Exhaust - heating up the bumper

wondering if my new ws2 exhaust will begin to bubble my paint or discolor it while it's being driven and heating up...so far after i've been driving I can place my fingers on my bumper cut out thing and hold them there without it being too hot...should i be worried about this? i've seen it happen to other cars...i have enough clearance it's just that the tip could come out about half an inch further but i don't see anyway in making that possible...should i be concerned?

The only time you should worry about this is if it's in contact. If it's open in between, there is plenty of air ventilation to keep it cool. My RS*R sitts pretty close and I have had no problems.

pretty sure my exhaust rubs against my rear bumper a little bit and when i examine it theres no melting/burning, so i say dont worry about it. I dont think it'll be held against the bumper long enough to do any damage

don't worry about it. it doesn't get hot enough

thanks for the response guys!
