09 530 smrr dual exhaust on a 08 510 smr?

Ive been trying to find exhaust systems for my 08 510 smr, and I could barely find any, so I came up with the idea of buying a dual exhaust system off a 09 450/530 smrr to fit on a 08 510 smr. Would that work and will there be any power gains? My bike already has a single arrow and has dynoed at 53 whp, but Im pretty curious about fitting a dual pipe off a 530 smrr.

I would say you can get little bit more mid range maybe, but you get way more better look and sound.
If i have understand you need from that SMRR bike that rear frame, when there is two exhaust bracket, rear bumber/side plastic, when they are little bit different shape due those silencer, not sure would you need SMRR airbox could you use 2009/2010 SM450/510R airbox. So that exhaust is not bolt on, or you can do your self, getting some one weld that bracket in that rear frame, then bend those rear number plastic and see what changes need in airbox

damn sure the airbox is the same for all the models... just get a better flowing single muffler, less weight...
