Just put in my cz revi and duct today...the car sounds really nice and im about to run it around for the night. But when I was revving it in my garage some black oily looking stuff came out of both exhaust tips. Is this common with a new install of either of these mods or is it a problem?

I'm sure it was condensation mixed with soot. It happens all the time when my car is cold. Go touch it. Is it black water?

Its probably just soot.

I think it was just some soot and being blown out from the first time in using the mods. I've been driving it since last night and havent seen the problem again. Also i just used some never dull on the tips so i'll see how much buildup there is after a tank. Thanks for all the help
