just wondering if anyone has ever tried Teflon tape or chamber seal exhaust tape to seal their exhaust on a pan. My spigot is not loose enough for shim stock all the way around. That was a beer can though, maybe I should try some thinner shim stock. I'll see what I've got at work, but any other suggestions would be nice. Something cleaner than silicon.

Never heard of using teflon tape for exhaust. Something you might want to keep in mind though: When heated to 446 degrees F. teflon starts to outgas some harmful crap. As the temp increases, more and more nasty gases are released. By the time you reach 1000 degrees F. teflon emits the equivalant of phosgene gas. That was the deadly stuff used in trench warfare in World War One. No Thanks :D !!!

Regards,
Geo.

My spigots aren't in too bad of shape so i can get away with using the orange exhaust seal goo in the tube.

A few friends with screwed up ports have tried slipping the pipe on the head, wrapping the pipe that the clamp slips over with exhaust wrap and then putting the clamp over the exhaust wrap. works pretty good.

Pan exhaust spigots are tough to seal once they are worn alittle. The orange stuff you talked about is the best. Have used alot of beer can shims over the years. The exhaust sealing silicon is messy but if you seal them let it set for a day or over night wipe the excess off you should not have any trouble, and should look clean. Good luck.

I have used Wurth RTV silicon in a Shovelhead and Panhead pipes. It won't melt and I have let it dry for a day before riding. I heard that it can be used in all exhausts except turbocharged.

Permatex Ultra Copper RTV is designed for exhaust manifolds etc. and it even withstands higher temperatures than Wurth.

I've cut some thin slots in the pipe at the head. That lets the pipe collapse some on the spigot. Use a good clamp.

Its worthwhile spending some time when mounting the exhaust to save yourself some trouble down the road. Most of the damage I've seen on pan exhaust spigots is from janky-ass pipe mounting especially on the rear head. The way the stock system mounts is pretty solid, it keeps the pipes where they need to be, but you still have to tweek and adjust so every thing fits into place nice and snug without binding.
