How to Repair a Split Exhaust Pipe

Updated February 21, 2017

The exhaust pipe of an automobile is located between the engine exhaust manifold and the catalytic converter. As a result of heat from the engine, the exhaust pipe is susceptible to metal fatigue. Besides the engine's conspicuously louder sound, this fatigue can cause cracking or splitting along the length of the exhaust pipe. When this condition is allowed to continue, complete deterioration of the pipe will occur. Until the exhaust pipe can be replaced, you'll need to temporarily repair the split.

Place the vehicle's transmission in either Park (if automatic) or first gear (if standard), and fully engage the parking brake.

Raise the vehicle to a sufficient height with the auto jack, and position the jack stands on the frame sections of the undercarriage.

Place wheel chocks firmly on both wheels that remain on the ground.

Wrap the exhaust pipe repair kit tape around the split pipe according to the manufacturer's directions. The tape will bind to the exhaust pipe with the heat generated by the exhaust system.

Tip

There are several products on the market for repairing automobile exhaust pipes. But you may want to delay the purchase of any such product until you have inspected the pipe for the degree of damage.

Warning

Consider this form of repair as temporary only. Your engine's exhaust pipe should be replaced as soon as possible. There is always the possibility of carbon monoxide leaking into your car as the result of a failing exhaust system, so take your car to a repair shop right away.

Things You'll Need

  • Auto lift jack
  • Pair of jack stands
  • Wheel chocks
  • Medium-grade sandpaper
  • Clean cloth
  • Exhaust pipe repair kit
