    Ok, tell me if this also sounds like a clogged cat. When i cut out my muffler to replace it, black gummy stuff shot out all over my undercarrage, and now, it puts out a little black smoke every time i start it, which im thinking is because i have less back pressure and its blowing stuff out more, what do you guys think?

    im positive i dont have blue smoke, and it doesnt smell like oil, whats the gooie black crap that came out, is my cat sound like its plugged or not, and if it is, does that effect the sound volume?
