whats wrong? test pipe? running rich? tip 2 close?
now my question is:
what causes the black crap/soot/carbon that builds on upon the back bumper?
we all know it's when the engine exhales... so, any ideas?
no cat? meaning you're running a test pipe/straight through? or you're running rich? or even just because you're muffler exit is a little too close to your bumper?
anybody with an s2000 run a straight pipe experience this?
i searched but nothing specific came about.

Most of that shit(unburned gasses etc...)would normally be burned in the cat;but,as the cat is not there anymore,you collect it on your bumper.
Start cleaning.!!!

what if my car was bone stock with just a test pipe...? stock exhaust, header, and no sort of fuel management....
will that lower my chances of the blackness stuff on my bumper? i'm thinking of riding around like that but somebody told me the black stuff is usually and mainly due to the non-use of a cat.
