There is no sensor in the mufflers. The entire stock exhaust from the cats back will come off as one piece. No cutting needed. I had mine installed at a show and I watched them do it. It took them maybe 30 min. Making sure the exhaust tips are lined up actually took the most time. I have had the system on for 2 months now and have never had a light come on. Hope this helps.
