I just noticed the difference between the left and right exhausts...has anyone ever tried running two right side pipes, ie put a right pipe on the left side, to get a little more flow and tone...

 

The stock and SE mufflers have a detent section on the inside of both of them to clear the axle/swingarm.

Maybe if you went with smaller diameter aftermarket slip-ons it may work but not sure at all, and also not sure how performance would be affected.

 

In addition to the detents, the left muffler (on the '09s anyway) is nothing but an echo chamber. I'd think two right mufflers with their restrictive baffles would smother your poor engine.

 

knocked the plug out of the closed muffler on a 10 and she sounds good now also removed cat

 

The rear mounting bracket on top of the mufflers will not bolt up.

 

You will lose even more bottom end. Ride a 2 into 1 and you will know why.

 

Yes it will
