I have a 2008 Max IV with a Kohler Command 25 H.P. engine. When I bought it , the tail pipe that sticks out the hole in the engine cover was missing . The heat from the exhaust is starting to melt the black trim around the hole in the cover. The muffler could use replacing , but I can’t find a listing for it anywhere. I found similar mufflers , but none with the tail pipe. I also found a tail pipe , but the listing doesn’t say it will fit my muffler. Anybody else run into this problem ? Any help will be greatly appreciated.
