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?
