No you don't have to remove the exhaust. You'll have to remove the air intake with boots and then the carbs. These are located in you fuel pumps on the side of the carbs. I usually toss them out and get a good inline fuel filter. Also, Ski-Doo used filters once that just pop into the fuel inlet nipple but haven't seen those in a while. Maybe these are the same size and will just slide into the inlet nipples on the pumps.
