Re: aq 125 /270 leg...exhaust pipe
You will have to remove the engine, and to remove the engine you can remove the upper gear box (Keep things clean and don't loose the shims and new orings going back together) the exhaust bellows hooks to the end of the exhaust pipe, and you might be able to get the pipe unbolted and the bellows off without removing the complete drive, but it's a LOT easier to remove the complete drive.
