It differs only slightly from the OEM but fits perfectly. On the standard part of the suspension, the rear silencer is chromed and welded on. Difficult to remove without damaging the rubber part of the suspension. I suggest you cut the pipe to the back of the muffler so it's really free from the front pipe. Then leave it on the ground and pull it out of the harness, hopefully without damaging the rubber piece. You need to carefully cut the old muffler pipe from the front pipe. I use metal snips and a vise to unscrew it.
