I got a 2007 satin white (pearl white) WRX and its got a turbo back catless exhaust...so its been about a month with this new exhaust system and ive noticed the bumper near the tip is starting to change color...like a yellowish brown.


Is this beacause of not haveing cats or what?

How do you protect the paint or fix this?

get ur car tuned.

Get a bumper exhaust guard or a better tune.

I'd be leaning towards a tune.

do guys know of a good bumper exhaust guard...i mean i found some but they are around 130 for a little piece of some bs plastic or carbon fiber

vote number three for the tune.

Get a tune

tune it.

make sure to wax it and take some rubbing compound around the area and try and keep it clean so it doesnt ruin the bumper even more...

yeah it because you have no cats on the car

i would say go with both, but a tune would should be the first way, but sorry if i am hi-jacking, but has anyone seen this happen to any other bumpers such as OBP? i won't be able to get my tune for a lil over a month or so but the car will be driven rarely, would i ruin my bumper also?
