I have a 2006 Apex GT with 6,000 miles. I have had the exhaust donuts replaced but within the past 200 miles or so I have noticed a slight quiet back fire that has progessively but slowly gotten worse. The past ten miles of me riding it I had one loud back fire but only after running it hard through the trails then backing off the throttle. Does this sound like the Y pipe and Exhaust Donuts? I have a trip planned this up coming weekend If I dont fix them before I go could I cause alot of harm to the engine or sled by riding it?
