Black stuff from exhaust?
Sorry for the retarded topic title, as mentioned in a few other topics, I'm new to the Honda game. I bought a car recently (93 civic ex with a 95 si D16 swap), and it already had an exhaust on it, of course lol. I later found out it was an OBX exhaust, which I also later learned, is garbage.
Now my question is this. I have black stuff coming out of the end of it, and building up on my rear fender. It's nothing extreme, but there is a slightly noticeable amount and I was wondering if this is normal, if it's bad, or if it's just a downside to having a garbage exhaust.
If it's a bad thing, what could be the possible cause, and where could I be directed to fix it? Thanks again.

I got a buildup on my 00 ex but its because I have leaky valve stem seals and I burn oil after my car sits, causing the buildup and crap to accumulate as it blows out my exhaust.
doubt that helps you but its what my deal is.

its from running rich if its like a black sooty buildup.. i noticed it too after i put my exhaust on could be a bad O2 sensor or bad cat but its hard to guess exactly what it is other than most likely you are running rich or burning a lot of oillike the previous post says

Ok, good thing. I just figured out what the check engine light that was coming on was for, and it was for the O2 sensor. So I'll see if the black stuff disappears. I plan on replacing the crap exhaust soon anyway.
