My thoughts exactly b/c you'll probably want a means to self-tune the bike w/new exhaust system & also a good time to do the stage 1 air to really open it up. Don't want the engine running too lean...
Just out of curiosity, why are you putting the 2010 pipe on the 09? The 2010 pipes have the cat converters in the head pipes, which are more restrictive and create more heat. I think it will do more bad than good. Just my opinion..
