I have known for some time that my cycle had a slight exhaust leak where the header pipe meets the muffler. It was never an issue because it did not seem to make it run worse and I would only smell it while sitting in traffic. But since I installed the Vetter Windjammer I smell it CONSTANTLY while going down the road. You would think that it would be possible to leave the annoying smell in the wind, but not so. I am not even sure if the exhaust system I have is factory or aftermarket. I may need to learn how to install the exhaust seals, but I am not certain what type will work or how to install them. Experts?

The seals are pretty easy to change. Unbolt the two nuts for the flange at the head, loosen the bolt on the clamp at the H-box and work the header out. I don't think you will have a hard time getting yours out since it sounds like they are all dried out and cracked. Clean the inside of the h-box connector so there is no old gasket in there as well as the end of the header pipe. Slide the new seal on the pipe and work it back in the h-box. Tighten the flange first to position it and then the clamp on the h-box.

Here is a link to the Gaskets I have used them several times and they work great.

Good luck.

That's one end, the ones for the other end of the H-Box are far more difficult to find. While people have used plain muffler cement of aluminum foil to replace them I think CXOkie erplaced the bad one I had by carefully rolling aluminum foil with a coating of some sort of furnace or "stays slightly flexible" muffler cement on it.



The exhaust has cooled down enough once it's coming out of the H-Box that you could probably use a Permatex product instead along with the rolled piece of foil to get the thickness.

I just double checked. The leak is on the left REAR H box/muffler area. I will try to buy a new seal tomorrow.
