I have a severed exhaust pipe, just a little in back of the centerline of the front tires, right before what I think is the catalytic converter. Unfortunately I dont have a photo now but the sever is also next to what appears to be a flex or ribbed pipe. I think I might be able to fix it with some heat-activated epoxy-fiberglass tape and a clamp. Does anyone know what the pipe size is here? I want to buy the right-sized clamp. And if you have any other advice, it would be appreciated. Thank you.

It could be 1-3/4 or 1-1/2. I would suggest to cut a tin can in half length wise then wrap it around the leak, using Stainless steel hose clamp that should last for awhile. Fiberglass tape might not last long.

Won't there be a gap around the aluminum? I guess there may be a high temperature caulk/seal/cement at the parts store I could use. On the stainless steel hose clamp, do you mean the simple ones used for coolant hoses or the bigger ones in the exhaust section? Can it be confirmed if the diameter is 1-3/4 or 1-1/2, or were 2 different exhaust sizes used in the 1999 CRV? Thank you!

You could take it to a shop like Monroe Muffler
where they could weld a piece of new pipe
where the split is.
The one in my area does this type of work
and it's a better fix than you're thinking of.

These fixes you guys are speaking of are all a bandaid that will last days at best. You can't put exhaust back together with Fiberglass tape. A soda can, that will maybe hold for a few days.

Go to a shop and have it fixed properly. Doesn't require a bunch of work. They simply cut out the bad part and weld a new piece in.

I think I said that.
But Thanks
Do you have to get upset when someone says something similar to reinforce your point? May want to have a beer or whatever to chill out.

People don't take one person's opinion alone as a reason to make a choice (why websites have reviews and so on). So I said the same thing to reinforce that it's the smarter way to go.

I'm really low on cash, can't afford a muffler shop and would rather do it on my own which is what this forum is all about to my understanding. The only self-solution mentioned here I think was the aluminum can idea, however I saw exhaust steel sleeves that look tougher that can fit over the ends of both pipes & exhaust clamps used at both sleeve ends. About a $15 repair. I will jack it up to figure out the pipe OD and see if there's still pipe integrity.

It's a pretty easy fix and you're just
going to make it complicated and not
going to fix it right.

Hey, I understand being Low on Cash.
I tried your method ONCE on a Camry I had
and ended up going to Monroe Muffler where I had a Piece welded in.
The Temporary Fix was Just That.
When you get the cash, go get a Free Estimate--Most shops give them.
One of the dangers of NOT fixing it properly is Exhaust Gas getting into
the car cabin and making you sleepy.
Really, a Free Estimate cost nothing but time.

If the split is next to the Flex,
you might have to replace the flex too.
It depends on the integrity of the pipe.
Go under the car and measure, don't guess.
You could just cut the pipe out and run
without a Muffler--The neighbors will love you.

Fubar what u wrote was key. There IS no flexpipe. The last I addressed this, taking it to a Monroe, the guy said that the prior owner of my CRV welded the resonator to the manifold as a straight pipe. He said that my Honda didnt come with a flex-pipe but used flex-bolts (springed bolts I guess) in putting the exhaust together, that the straight pipe had no flex, and its rigidity caused the pipe to break. The extimate to repair was over $2000 with a new manifold and everything on back.

$2000 is not an option for a 21 year old, 200,000 mile vehicle that I paid $500 for. What I was thinking of doing is to hacksaw out a section of that broken pike and install a flexpipe with clamps. Athough the original used flex-bolts, I think that this would be the best least cost solution. What do you guys think?

Well I went to a different Monro and they said they can weld a pipe in there for $40, so I did that, for now. The pipe Dia is 1-3/4". What I will do in the meantime is find the shortest 1-3/4 flexpipe I can find to install there for the next time it breaks or before it breaks again... there isn't much length between the manifold & the cat to work with.

One thing I notice now when climbing a hill, lots of white smoke coming from the exhaust. The water level in the radiator is fine. The welding mechanic said he picked a few leaves out of the cat-converter end and wouldnt doubt there was more crap in there. Is this a concern? Hopefully it will just be temporary?

The pipe section you guys are talking about connects th exhaust manifold to the cat. It's really easy to take out (7 bolts and it drops). Just get a used one at a junkyard and bolt it on. The old pipe is not worth fixing.

The only difficult part is that you have to make sure to transfer the o2 sensor over. It's really not that hard.
