Indeed, send Drew at Dr V-Twin a PM when you are ready for parts, he gives forum members some pretty good pricing. and great service.

I've heard good things about that pipe. I'm curious though. What kind of improvement are you expecting with just doing the pipe without going to a high flow a/c?

not expecting anything at all! untill i get an a/c and a tuner! just want the pipes because the stock ones sound so weak! but also want the extra power when i do decide to tune it

Some folks are good at talkin some are better at listening. I've been wrong before and I'll likely be wrong again, but unless you're replacing pipes with the same back pressure profile as what your taking off you'll change the flow dynamics. It's good to be an American, do what you want and enjoy the ride.
How can changing how the exhaust waste leaves the motor affect the AFR before it is ignited so as to make it leaner?
My understanding of the 4 stroke IC engine makes your theory impossible, but I am always open to an education.

+1 on ThunderMax w/ AutoTune (TMAT) ... it replaces the entire stock ECM ... have not looked at their website to see if they're compatible w/ the '12 models yet, though ... I understand there are some pretty radical changes to the electronics on the '12 models (I think they split the boards up between 'chassis' and 'motor') ....
I am super-pleased with my TMAT ... and the performance I've been getting

Rich if you had a significant difference in flow characteristics of the pipes (scavenging, for example) ... it could change the characteristics of the fill rate of the combustion chambers at higher RPMs ... doubtful it would be noticeable on a stock motor under 'normal' street riding conditions ... I can't really formulate a theory on how it would affect the EFI ... if it was a wide-band O2 system, the ECM should notice a richer or leaner condition in the exhaust under the affected conditions and compensate ... however, with narrow-band O2 sensors it might adversely affect the AFR ... just thinking out loud here ....
