Running Rich?
I have noticed a black residue over my exhaust on the back of my car. Has anyone had this problem? I'm running a stock SC setup on the factory tune. The only other mod I have is a full exhaust. Do you think in may be running rich? I also am not running the secondary cat which may have something to do with it. Any help is appreciated.

I know it is normal for some but I have black stuff all the way up to my spoiler. It that still normal? I never noticed it till I had my 2nd SC installed. I also noticed it seems to run much better with the 2nd one.

all the way up to your spoiler....Maybe your exhaust does not stick out far enough..
