If you are trying to retain the stock muffler then you will still need to cut. If you are going to swap out the stock muffler too, then you can pull the stock exhaust out as one unit from the primary cats all the way back. And 60606 will just bolt right up. I just went though this. However, conventional wisdom says (as cited by a couple of other forum members and I took their lead), you need to replace the stock sealing joint coupler just behind the driver side primary cat with the Borla provided Accuseal clamp and the rest is easy peasy.
