How to Tape a Hole in a Muffler
Believe it or not, its actually possible to tape a hole in a vehicles muffler, as long as the holes not too big. Generally speaking, if the holes larger than two inches in diameter, it cannot be adequately repaired with tape. The tape used to repair holes in a muffler isnt the kind of tape that youre used to using; its a special kind of tape, also referred to as a muffler bandage. This bandage material is made from fiberglass and a special resin that seals against the muffler once the pipe heats up.

Park the vehicle and let it cool down for at least two hours before proceeding. The tailpipe can exceed temperatures of 250 degrees Fahrenheit, causing serious burns if not allowed to cool down.
2Lift the rear of the vehicle with a jack and support it with two fixed jack stands. Locate the hole in the muffler and measure it with a tape measure. Verify that it doesnt exceed two inches in diameter. Holes larger than this are simply too difficult to bandage with muffler tape.
3Clean the area around the hole with a wire brush to remove as much dirt, debris and surface rust as possible; this will ensure a better seal with the muffler bandage.
4Open the muffler bandage kit and unravel the bandage. Wrap it around the muffler or pipe where the hole is several times in a similar fashion to an athletic bandage applied on a person.
5Wrap the bandage with the wire included in the kit to secure the bandage to the exhaust pipe. Twist the wire together at the end and crimp it with a slip-joint pliers to ensure that it doesnt come loose.
6Start the vehicle and allow it to run for 20 to 30 minutes; this heats up the bandage. Turn off the engine and let it cool down until the exhaust has cooled to room temperature; this completes the sealing process. Turn the vehicle back on and check the bandage for leaks.
