How to seal slip-on to header
This last weekend I rolled the Ultra out from it's storage spot in the garage. It was parked into the sun when I bent down with a flashlight to look up the exhaust to be sure there were no critter nests in the exhaust pipes before firing the thing up. I have V&H true-duals and turndown mufflers installed. The turndowns have no baffles so I can see all the way forward. I noticed there was lots of light coming through were the header clamps to the muffler. They are bolted together as tight as I dare....how can I seal this? Will I high temp sealer work or is it too hot there for that? The distance to the clamp on the left side is only a couple of feet...how hot is it there? Thanks in advance for the ideas!

Beer can shims.....Drink a couple of your favorite beverages, then cut rectangular shims outta the cans with a pair of sharp scissors. Put the shims between the clamp and the muffler flange. It will make the clamp grip tighter and seal the slits in the flange. I have been doing this for years to fix pesky leaks. It is a near must on an Ironhead where the pipes clamp directly to the exhasut ports on the heads. Works far better than goo in a tube.

sealer and shims are not req'd............however, correct installation is. As mentioned, use the new clamps, and make sure the muffler is fully forwarded onto the head pipe. The clamp should be at the very forward end of the muffler. Don't be afraid to CRANK DOWN HARD on the bolt/nut with a 1/2" drive ratchet or bar. My right side mufflerkept working loose until I did this, and now the issues are gone. Plus, muffler removal is a snap.
