carbon build up on exhaust

[jwahl16]

Hello, I just put a new 3" turbo back exhaust on and after a day of driving I already notice carbon buildup on my muffler. I know we run rich from the factory but is this normal so soon?

Yes.

Carbon in the exhaus is normal on all cars, carbon on the bumper is a poor exhaust.

Please don't post incorrect information.

Carbon is the by product when the fuel is burned just like diesels have the black smoke. Anytime you see a car with black smoke coming out the exhaust it is very very rich.

Or no cat installed.

yeah i don't have a cat, i don't have black smoke, just carbon/soot developing on the inside of the muffler.

Thanks again
