So I removed my exhaust today and I was cleaning up the area where I cut the stock pipe to install my slip-on can and I noticed there is a perforated pipe inside the exhaust that's about two inches long that has insulation packed around it. I can't believe that I didn't notice it there when I installed the pipe (must have been too excited to get it on). Anybody remove this thing? Seems pretty well jammed in there. Might try to cut it out somehow. Any ideas?
