Getting brown residue on rear 1/4's white T

[RUQWKNF27]

I figured by me extending the tips it would help this but has anyone else had this problem. Again it gets like brown or tan from the exhaust right above on the body where the exhaust comes out.. I have a white T so this is very apparent when you see it.. Only thing I can find to get it off if purple degreaser an i'm sure that is just wonderful on my wax ...LOL

Sounds like you got something going on with the motor. You might ask in another area. I don't know alot about the turbos. I'm on my learning curve. But that purple cleaner is not helping your paint at all. It strips the wax off right away and leaves you no protection. It will eventually discolor your paint.
