I am looking for a way to repair a small hole I created in my exhaust. The hole is about 1 to 1.5 inches long and only about the width of a cutting wheel (you can guess how the hole got there). I was considering using a jb weld type product but i fear that it won't fill the hole i created.

Any advice is appreciated, thanks.

You can use a wrap and clamp to seal the hole. Your local parts store should have such a kit.

Or the better solution would be to weld it shut, or cut out the section of pipe where the hole is, and weld in a new section of pipe to replace it.

  • I'd definitely recommend the welding option. Clamping the hole shut will do little to nothing to strengthen the tube, whereas a good weld will restore it to its original strength. This gets more important the further away the damage is from the closest mounting point.

I think you're looking for something approximately like this, only in the size you actually need: exhaust band clamp
