I don't know if resonators and mufflers are the same. There's different internal designs when only looking at inlet/outlet size.
Been reading too. It looks like it's a shot in the dark just from so many choices. To add to any confusion, people even try 2 resonators one after the other.
My direction is also toward the longest that'll fit. Diameter of the muffler/case could be an issue for ground clearance. Dunno how much is too much there, but it looks like 6" might be alright. (2005 GP)
Cost, do I get a cheap one and hope it does ok? Or, try and get a better one that might outlast my stock mufflers to use later?
