Did they remove the resonator on the 2011? I was under it, and could not find one in the back. I can see that the last part of the exit tip 9 roughly 15" long ) is slightly larger than the pipe, and I flashed my light inside it just in case, and no holes or anything. And from that part , to the muffler, all same size, so I guess resonator is gone ??? Also is the diameter of the rear pipe from the muffler 2.25" ? Thanks
