When I first got the car I had to wash it frequently, the black soot builds up on the rear bumper and bottom near the exhaust tips, even on the rear quarter panels, but now that its turbo it really builds up badly... Everytime I take it out I have to wash the rear bumper now, even if I only go and cruise for 20-30 mins., what can be done? Its even starting to run up to the tail-lights and top of spoiler I find black dust particles. I am not running with cats on my exhaust but I do not know if that would even help its a magnaflow exhaust and I would like to know if anyone else has this problem and what can be done about it? The stock exhaust did it, but not nearly as bad as it is now...Thanks for any help with this prob.
