Your bike is almost certainly running lean. It starts that way from the factory and the new pipes only made it a bit more lean. Clearly, it is not as lean as it would be if you also had done the air cleaner , but it also clearly isn't running as strong as it would be with the air cleaner opened up.
My opinion is that as soon as you can swing it financially.....get the A/C and stage 1 reflash. If you plan to be constantly tweaking your engine then skip the reflash and get a power commander.
As for the blue pipes.....if I held my breath for 10 minutes I'd turn blue and any doctor would say it was normal....but it wouldn't mean it was "OK"
