Gen4 to Gen5 Exhaust Compatiblity

So I've had a chance to try to test-fit a Gen5 full stock exhaust (Cat-back) on a Gen4 and it didn't fit. It seems like the part that is different between bikes is the not so much the location where the manifold ends but rather the location of the bottom mounting point, which Cat bolts up to. That obviously doesn't really matter since nobody will be swapping stock exhausts between bikes but what is great is that aftermarket exhausts don't use that mounting point at all. This means that aftermarket exhausts should fit both bikes. This includes slip-ons and full systems. Has anyone tried it yet?

Why? Are they better?

And does that mean the rest of your exhaust is designed for gen4 and it mates up with gen5 headers just fine?

I have a yoshimura alpha 3/4 system for the gen5 on my gen 4. Only thing that had to be done is remove the gasket donut out of the header side. As well as the mounting point under the rear set doesnt match up. But the passenger peg mount holds it nice and tight

So it seems like location of the foot peg mounting points has been also changed on a gen5 from gen4.

Maybe not. I recall hearing that the gen4 header is longer then the gen5. Overall lengths are rhe same but with the longer gen 4 header and the longer muffler section would put the mounting point off. But if you swap the gen 5 header with the gen 5 muffler on the gen 4, it should line up.
