I have a 2003 Mtn Cat 900 chassis, with a DD 1010 kit. When I go into deep powder and start carving through a lot of snow, my engine starts to really run rough. If i get in the open and have a good run to "clean" it out, it runs fine again. I have heard that the silencer can fills with snow and causes the engine to run crappy. If this in fact why it starts running bad, does anyone have any solutions, mods, retrofits, etc. that would solve this problem? Is there a kit to relocate the exhaust outlet to a place comparable to the new M-series chassis? ANY HELP PLEASE--THANKS!!!!
