How to Repair an Exhaust Pipe
An exhaust leak can be dangerous (double exhaust pipe image by green 308 from

Having a hole in the exhaust of your car is one of those nuisance repairs that need to be made. Not only can a hole in the exhaust add to the noise level of the car, quite substantially at times, but it can also allow fumes into the passenger compartment. Without a welder, there's really no way to create a permanent fix for an exhaust, but there is a fairly easy way to eliminate the hole in the exhaust until you have the time and money to get a new one.

Skill level:
Moderately Easy

Things you need

  • Can opener
  • Tin snips

  • Flathead screwdriver

  1. 1

    Remove the top and bottom from a tin can. Use a normal can opener and an empty food tin.

  2. 2

    Rinse the can out thoroughly with hot, soapy water and wipe it dry with a towel.

  3. 3

    Cut a straight line through the can with a tin snips.

  4. 4

    Locate the hole in the exhaust. You'll want to wear some work clothes for this operation as it requires sliding around under the car.

  5. 5

    Place a metal hose clamp on either side of the hole in the exhaust. Secure, but don't tighten down.

  6. 6

    Slide the tin can over the hole in the exhaust and squeeze the can until it's tight around the exhaust.

  7. 7

    Slide the hose clamps over both ends of the tin can and tighten the clamps down with a flathead screwdriver.

Tips and warnings

  • Always let the car cool for at least an hour after running it to make sure the exhaust pipe isn't hot when performing the repair.
