So I am riding last weekend with a group of rzrs and we do a 120 mile trip. Part of the trip involved a high speed run down a power line road. By the time it was over my heat shield had melted around the rear of the muffler. So I find out that the spark arrester had come loose and was blowing hot air on the shield. So does anyone have a stock muffler for sale. I don't want to put any more money into this machine than I have to. I am going to replace it next year and just need it to get through the year.
