patching an exhaust leak
I have an exhaust leak on one of my pre-cats, and my inspection is about to be due. I know there is such an animal as an exhaust patch kit, but I was wondering if JBWeld would be able to survive the heat of the exhaust, or some similar product.
any thoughts? Skip

You have to cut out the perforated metal pipes, and replace them. Since the pipes are only 1.61 inches in diameter there, you probably have to take it to a welding/exhaust shop that you trust, and have them fix it for you. Hopefully they can fix the rusted tube, or more likely just weld in , say a 1,3/4" tube, about 4" long and just replace the flex coupler. This is assuming you want to do this cheaply.

Hi Tom,
Would flex coupler = exhaust gasket on subaruparts.com?

Once the exhaust is rusted through, it's pretty tough to weld It doesnt ground well, and since it's rusted thin, you tend to burn through alot
give welding it a try, but odds are you're probly better off having someplace make you new front pipes. You can order resonators in place of the cats, and it ends up being fairly inexpensve

I've patched small holes and leaks in exhaust with JB Weld. My ex-wife backed into a curbe and severed the pipe between the cat and the muffler. I took a 2" pipe, cut it down the middle, put it over her pipe to hold it together, used 2 hose clamps to hold it in place, jb weld all over it, let it dry, started it, found tiny holes i had missed, patched them, and it was good as new(unless you actually looked at it...)

actually, my leak is a split on the seam on the pre-cat, I put jbweld on the seam, and I will see how it does tomorrow I guess.
