Time to fix up the ivertaflow

My muffler came with a very bad JB Weld patch job on one side and now the other side is starting to unravel so it time for a repair. Easy enough to cut out both pieces and replace them with some pieces of Centek exhaust pipe. My question that I don't think anyone has ever asked is what kind of resin to use for the repair?   

I've found a place that sells fiberglass sleeves which should make a it real easy to make a decent looking repair, but they mentioned something about standard epoxy resins only being good for about 195 degrees.   High temp epoxy is out of the question, wife would have a fit if I cured the muffler in the oven. Not sure if I should be concerned about this or not, definitely don't want repair to melt, but I would prefer to use epoxy because I'm familiar with it.

No, taking the muffler out is not an option, it would require $1000's of new stereo equipment to overcome the noise not top of the $1000's already spent.

Shoot a temp laser at the invertaflow entry hose. I bet it's lower than 195..... You aren't epoxying the exhaust manifolds..... but that's coming from a hoser!(sic)

Take it to the Gas Monkey Garage-- He'll fix it

I just fixed the muffler on a boat I recently purchased. One inlet was crushed and leaking and the main chamber had small pin holes all over it. Rather than replacing the inlet I pounded a section of SS muffler tubing into it. I think it was 2 1/2 inch and it fit perfectly. You can either use the tubing or if its slightly larger then use a tubing coupler. Then I sanded it and put on a couple coats of resin. I just used the bondo resin from Lowes. I haven't run it yet so I don't know if my repair worked but I think it will be OK.

I think you are overestimating the sound difference in removing it, and it really frees up working on the front of the motor. I would be surprised if you would even notice a difference noise wise

It could be my lack of hearing although my martinique was much louder than my bfn. At speed that is

I have almost exactly the same situation, leaking invertaflow, hack repair by PO, and the same questions regarding resin. I will follow your thread with interest...

That's more than pipe will take, I think it begins to fail about 350. The ends of both inlets sides are frayed where they end in the big chamber, I replaced the rubber exhaust pipe last year and it was cooked and a little mangled on the inside. I'm guessing this is all from a blown impeler, it would be interesting to know how long it takes everything to happen once the water stops flowing.
