    Exhaust problem

    I currently have 2.5 inch piping with no cat and a dtm tip muffler. I just got the car painted and im getting carbon dust all over the back of my car. What should i do to stop this? new tips? add a cat?
    thanks

    Typical of DTM style tips, they also tend to be the noisest. Cut them and flip them and your car will be mega quiet and clean.

        a high flow cat would help as well. white cars suck for this kind of thing.
