Re: exhaust donuts
Put a steel sleeve inside the donut like the factories used to do. It's a short piece of tubing with a swaged-down end that slip-fits into the pipe, protecting the inside of the donut from the fire.
They also make steel donuts, but they tend to leak if things aren't lined up just right. |

Re: exhaust donuts
You can still buy the donuts with the sleeve inside. Napa and Autozone both stock them in many sizes.

Re: exhaust donuts
Try the soft copper one. I did that to my Blazer and they are still in it.
