how to join exhaust pipe

[jungle_surfer]

I need to join two bits of exhaust pipe together. I had a big kink in it (insufficient departure angle when reversing down a steep hill), so I cut in in two to straighten it out, and now I need to join up the cut. It's in a position such that it doesn't have to be a particularly strong join, it just has to seal. Also, I can't get the cut ends very round, so I'm not going to be able to get it to seal end-to-end.

Any suggestions? Is it possible to slide a sleeve of some sort over the two cut ends and glue / weld it on? How about some sort of flexible coupling?

An exhaust shop can probably make you up a short flared pipe that you can clamp down onto the 2 pipes you have, or if you can afford to consume a few inches of the end pipe, then they can flare and cut that for you to clamp down onto the other pipe.

how about one of these... one of the pipes has been flared though.

easiest joiner would be a chilled carton













for the local exhaust shop to weld it for you

use a stick welder to get most of it and smear the joint with some silastic or sikaflex.

Yes its rough, But thats all i have here to use and it does work. wouldnt reccommend it on a top 10 nats car though

Thanks for all the suggestions! The two cut ends are really quite mashed up and out-of-round (the pipe had been bent flat, and it's pretty hard to bend it back to round using a crowbar!) so I think the solution would have to be something that goes over the outside of both ends, and is long enough to clear the messed-up part... A bit like what UDM showed, although mine's a lot messier. Besides, UDM you've got one pipe over the other, and then the 'bandage' over both, right?

How hot does it get down at the back end? A radiator hose wouldn't survive, would it? I don't need a really elegant solution, just something that works and will get it through rego!

Just take it to a bloody exhaust shop. I will only cost about 20 - 30 bucks cash. That would probably include a short piece of pipe as well. By the time you finish f&*^ing around and buying the bits you are talking about, it will end up costing more. Also if they (rego inspection) see bodgy things like that they will really start looking.

Wow, you seem pretty passionate about discouraging DIY attempts. I have a strange interest in trying to fix / build things on my 4wd by myself, but ok, I'll try it at an exhaust shop. If they'd do it for $30 I'd be pretty happy!

Mate, I love also doing DIY on my 4be but I agree with jungle exhuast shop $20 new bit of pipe.

I am sure there are other DIY things you could be doing.

Bush fix is a couple of coke/beer cans and some hose clamps with a bit of exhaust putty, would do the trick but definatly not pretty and not a long term fix.

I do all my own stuff, but some things just arnt worth mucking around with. And besides, your not describing diy, your describing bodge job.

It sounds like the pipe is too crushed and you would be better off with a new pipe made up.

Exhausts come in 3 sections so they can just make up a new section and just replace that bit.
