I need to do this as well. If I remember the post correctly, the idea is to drill a hole on the bottom side and insert a long sheet metal screw. The screw puts pressure on the internal part and pushed it up. Someone tried to drill into the insert and kept breaking bits. My understanding is that the screw just pushes up on the insert and "traps" it toward the top part of the exhaust pipe. HTH.

The screw fix is onlt temporary. Eventually, you will have to replace the muffler. They just aren't made to last forever. The fix would be for FFR to supply the system with the Lobac "auger" style muffler. By the time you purchase, ceramic coat ( for those who do) and take the time to instal, one has a considerable amount of time and money invested only to have to replace after 6,000 mi.
