Actually my intent all along was for an easy swap out, for the guys that are leasing. All that has to be done to return your factory exhaust is this; the section of my kit that slides over the cut off end of the factory one can be cut off and then you can either have a muffler shop weld the factory one back on with just one bead or use a clamp on style coupler and you are back to factory. Its about a 15 - 30 minute job. I may eventually add the extra pipe with the flange on a future kit but you are adding $100 to the price, and almost $200 if you want stainless. For now, all I am going to market it the current clamp on kit, because at that price I think most people will just pay an extra $150 for the Borla.
