Exhaust, what is this pipe?
So I tried to take pictures but they didn't really turn out, if you can't understand this at all I'll take more. So when I bought the exhaust off a member on here I was told the test pipe I was getting was resonated. The pipe I got does not look at all like a resonated pipe, instead it bulges out just a little bit from where a normal 3 inch pipe would be (.25 to half and inch) and on the inside I can see a bunch of bumps/knobs inside the bulged area of the pipe (bulge goes entire length of test pipe minus half an inch on either end. Is this some type of cat, or some specially built resonated pipe? Any clues? Its an AMS exhaust, but the pipe looks like it maybe made by someone else.
