This is not just a simple HO engine, the engine itself has gone through substantial changes which will change all of your aftermarket engine related add-ons. Possibly a can off of a M1000 would work just fine, and would not require any significant time to market, but the rest of the items such as Billet Heads, Porting, Pipe(s), Y-pipe, etc.... will be specific to the 2010- models. Since there have not been any significant chassis changes, most other items from previous years will bolt up fine.
It will be interesting to see if there is anymore power to be gained through simple bolt-ons such as Pipe and Head, we should start hearing more from Cutler, Speedwerx, D&D, etc... by Late August-September hopefully.
