does any body apply a small amount of silicone sealer between the joint faces when installing exhaust?

I did on my CBR600 D&D slip-on. It wouldn't seal up with the clamp provided.
Use some 'Ultra copper' (for high heat areas). Any parts store should carry it.

Its called "Permatex High-Temp Ultra Copper RTV Silicone Gasket Maker"
Its a product by 'Permatex' , 'Ultra copper' is for hight heat application. Its basicly gasket replacement material, so it workx uber-great on applications like tube fittings, ect.

http://autobarn.net/rodi/per81878.html heres a pic of the stuff, duno why it sez 4-cylinder / turbo app's. Works great on header manifold gaskets reguardless of cylinder count...

Canadian Tire has it. Lordco and Princess Auto also carry it. Good stuff and it's a big tube that will last a while.

As NFG said, its available localy. Goop up one or both sides, slip or compress yur pipe together, then you can wipe off whatever is visible with a rag. If its two flat sufaces getting sealed, I'ld use it sparingly, just a small bead (less clean-up / easier).

don't ask, but make sure it's dry before you start your bike and rev it. i was way too impatient to hear my exhaust, and now have high temp rtv splatters painted on the back wall of my garage!!! doh!

That Permatex stuff is crap. Trust me I have like 4 half used tubes at home.
Three Bond 1104 is way better. $10 at Carter

I used it on my exhaust too. the permatex stuff will break down when exposed to gasoline. Mind you mine is a 2 stroke, unburnt fuel is present in the exhaust. the copper stuff is also too soft i think.
I used the permatex copper on my cylinder heads with no problems it's just when exposed to gas it breaks down.

I used the Permatex on my CBR600 exhaust, worked great for 3 years.
I've also used it tons on cars/trucks. Never had an issue yet (exhaust manifolds / collector gaskets / Muffler seals).

thanks for all the explanations guys, i guess i'll try the Permatex stuff first since it's avalible at Canadian tire since i don't think they'll be much unburnt fuel present in my exhaust.

How I used the stuff is, smear it on both surfaces, let it sit for about 15 minutes until its a bit tacky before bolting the 2 pieces together.
I have always waited a day or 2 for it to dry. If it's not dry when you start it there is a very good chance it will leak.
