A car exhaust system channels the fumes from fuel combustion through the front pipe, into a muffler and out through the exhaust tailpipe. The muffler is larger around than the tailpipe and has baffles in it to reduce sound. Water, oil and road salt splash onto a muffler underneath the car. These items cause mufflers to rust and form holes or cracks. At this point, the vehicle exhaust is louder and does not keep auto emissions from entering the atmosphere. Repairing a muffler with Tiger Patch is much less expensive that buying a new muffler.

Things you need
- Dish soap
- Garden hose
Park the car and let it cool off completely.
Mix dish soap and water in a bucket to form a soapy mixture. Dip a washcloth into the mixture and wash the muffler. Rinse the muffler thoroughly with water from a garden hose.
Dry the muffler with a towel and allow it to air-dry completely.
Pull the loose end of the Tiger Patch tape off the roll. Hold the roll in one hand with the loose end pointing to the right. Stick the loose end of the tape to the top of the muffler about 3 inches in front of the hole or crack. Press the end down to adhere to the muffler.
Pass the roll down to the bottom left side of the muffler, pressing it down onto the muffler. Continue rolling the patch onto the muffler in counterclockwise circles until it is about 3 inches past the crack or hole. Overlap each layer of the tape by about 1 inch. Cut the excess tape off with scissors and press the end tightly onto the muffler.
Crank the car and drive it, or let it idle for 20 minutes to create a permanent seal on the muffler.
Tips and warnings
- Heat in the exhaust system warms the patch material so it sticks to itself and the muffler and seals cracks and holes.
