This is fairly normal after some time on a car. Before you cut your stock exhaust, take a long screwdriver (or similar object) and make sure the core (perforated inner tube) is still solid.
Also I forgot to mention. How come you think when I turn the muffler around a few times, smoke starts to come out of the tips? I noticed it today wen I was working with it. Thanks once again.
