While changing the baffles in my Rush slip-ons, I looked down into the muffler and could see daylight where the muffler attaches to the main pipe. I had read other post suggesting sealing the connection using a high temperature RTV silicone called Ultra Copper. Well I finally got around to sealing my pipes yesterday and wow what a difference it made. The sound is a lot deeper and throatier. The bike is just a lot more fun to ride. It made enough difference that if you haven't sealed your pipes; I think you will be pleasantly surprised at the difference it makes.
I bought mine at Auto Zone, but you should be able to find it at any auto parts store. As far as the application, I ran a bead around the inside edge of the muffler and slipped it on to the pipe from the engine and then tightened the clamp. You can look into the muffler with the baffle removed and see if you have a good seal.
Amen on the new clamps! You can reuse the old clamps, but they do not grip and squeeze like new ones. Get new ones, and get a long wrench to tighten them with, because the nut is hard to turn on the new clamps until the clamp reaches the end of its travel. With a short wrench, you might think they are tight but they are not. I think mine were about 8 bucks apiece at the dealer.
