Carbon in your exhaust is normal. I'm not sure exactly why it ends up on the bumper, but it does it on my car too. I think it has something to do with the aerodynamics of the car.
if you want the carbon deposits to stay away from your bumper, try having your exhaust brought out a little further, with a new piece welded somewhere in between. OR get a new muffler with an angle-cut tip.
I was a retard, and now I'm permanently banned.
J-cars seem to run rich from the factory.. it's 100% normal.
