A crack in the exhaust in your car can potentially hinder the safe evacuation of fumes and chemicals from your engine. Although often a cracked exhaust is not a major danger, it is really not a clever idea to risk it getting worse, or you could find smoke and fumes entering the body of your car. With a little know-how, it is possible to cover the crack on your exhaust pipe in no time at all.
Clean the crack in your exhaust pipe using a wire brush in order to remove dirt and rust which may hinder the repair process.
Remove the top and bottom from a tin can so you are left with the basic tubular shell of the tin can. Use a normal can opener and an empty food tin, and obviously remove any labeling on the can.
Wash the can out thoroughly with hot, soapy water and allow it to dry before you move onto the next step of the repair process.
Cut a straight line through the can with a pair of tin snips so it is now possible to increase or decrease the radius of the tin can tube
Put a metal hose clamp on either side of the crack in the exhaust you are repairing. You need to make it secure, but don't tighten down.
Slide your tubular tin can over the hole in the exhaust and squeeze the can until it's tight around the exhaust, covering the crack in the exhaust.
Slide the hose clamps over both ends of the tin can before tightening the clamps down with a flat head screwdriver.
