Replacing Exhaust Hangers?

[mstrjon32]

Simple question. A while back I lost an exhaust hanger on my Cherokee to rust and corrosion. I just cut it off and decided it could go on with one less hanger. Now I've lost another, way at the rear and I can hear it banging against the fuel tank heat shield when I start the car or go over bumps.

What are the odds that I can just buy some new hangers and bolt them on, without crushing the 10 year old steel pipe? Or should I just suck it up and replace the whole exhaust? The only leak in the system right now is a small crack near the manifold, that I wasn't planning on fixing anyway.

I don't want to put a cheap exhaust system on that's just going to rust away in another two years, but I also don't want to drop the cash on a Borla system, it's unlikely I'm going to use up the Borla's 1,000,000 mile warranty (but I might). It would sound nice though, I'm sure.

edit: Meant to put this in the Mechanical/Maintenance Section, oops. Maybe someone can move it?

I would suck it up. "Saving components" when doing exhaust ultimately just wastes time imho.

I once had a new exhaust system put on my Impala, the guy decided to use the old hangers without telling me; that was a good decision for about 20 days (I realize your situation is the reverse)

Just go to the nearest parts store and see what hangers they have in stock. Odds are you will be able to make something work.

If you want an inexpensive, good quality exhaust system, Dynomax is pretty good. They aren't rustproof, but their pipes and mufflers are aluminized so they hold up pretty well. A full cat back system for my truck is $160, so I can't imagine it would be much on a Cherokee.

You can buy generic hangers that will clamp on to the exhaust pipe (or you can tack weld it on if you prefer). They're cheap...just a couple of bucks.

You can get the generic rubber hangers with a couple holes anywhere. Bend some 3/8 or 5/16 allthread as needed. Attach a bent portion with a muffler clamp to whatever pipe is handy. Done!

Consider the factory locations balance the system rather well, invent your own and you can find it flexes in wierd spots, causing stress fractures where pipes meet mufflers or catcos etc.

Ended up buying some new brackets from the auto parts store and bolting them on. The old stuff cut right off and the new ones bolted on no problem. The rear pipe is no longer banging against the fuel tank and replacing the brackets that had given way on either side of the cat has quieted the exhaust down some, too.

Total cost for the brackets was about $6.
