The 09-10 models have twin O2 sensors don't they.
If so they have quite a bit of built in learning ability.Unlike my ole X1.
Not a 100% sure but could possibly get away with the self learnt tune(a workmate was told that by AMPS,he bought new 09 a few months ago).
Don't think ECM spy is working/updated for 09-10's.
You could also talk to John at TripleZ reguarding tuning,if needed.
As to exhausts?,What are you after?.Noise?.Power?looks?..the sound is a very personal choice.
Theres nearly as many threads out there for exhausts as there are oil..
Check out Utube for Buell sound clips..
Lots of good reading found here.
