Yea, don't use anything other than RTV or some similar type gasket goo. Paper or metal gaskes seeem to blow out and let the nuts work loose.

I've always used a small bit of 5-minute epoxy the muffler flange, It doesn't shrink, squeeze out, blow out or burn up...and when you want to remove the muffler a few raps with a screwdriver handle is all it takes! No leaks and no coming loose either...just put a very light coat of cooking oil on the exhaust port on the engine and the mating surface of the muffler then apply the epoxy and bolt the muffler up!

KSJ makes gaskets for the most popular engines. They get hard after a few flights so they don't loosen up when they get hot. Ron Lund usually has them. They will eventually leak/break but I've gotten as many as 70 flights before they started coming apart. If you check them occasionally, they work fine.

andre, i use 2hr epoxy between the engine and muffler, let it sit overnite, and use the red lock tight on the muffler bolts. don't use the epoxy on the muff bolts, because it will get in the threads and will mess them up when you have to remove the muff. doing it this way my muffs don't loosen or come loose for a long time. remember no muffs to tuff.......RONDOMATIC

I run with the red rtv myself. I let it sit for about 15 minutes before installing the muffler/pipe to the engine and have always been able to get a good seal. Christopher J

DO NOT USE JB WELD 
go to your local HONDA/YAMAHA dealer and get
YAMABOND 4 or 5, ask them which one dries into a rubbery substance, one dries soft and the other dries hard, id go with the soft, the hard stuff works great but requires a little more work to reprep if you take the exhaust off, the silicone just peels off. the Honda bond is the same way.

Make a gasket out of a aluminum pop or beer can.[This message has been edited by tr206 (edited 01-24-2002).]

It's best to use some type of sealant because when the engine warms up if not sealed it will leak and may cause the engine to lean out. It will still run with no gasket but could be inconsistent. I had a muffler fall off once due to paper gasket deterioration and that caused the bolts to become loose and back out. Most high temp silicon RTV from any autoparts store is fine and easily applied. It only takes a very small amount spread over the surface of the muffler flange and bolt it on. Absolutely no leaking and it even helps to keep the bench clean. I also have had success using nylon lock nuts on the muffler bolts.

I prefer KSJ gaskets. Easy to use, no leak, and no waiting time to put them to work.
