I recall seeing a thread somewhere or post that shows what needed to be modified to have the Borla tips (for example) on a TH with the tow hitch. I can't seem to find it any longer. Any help appreciated.
About 30-45 minutes with an angle grinder to remove the “lip” that contacts the exhaust tips. Not sure how this effects structural integrity if you are wanting to tow near the limits of the rating though.
