Anyone I have seen with this setup has not had a great experience, to say in the least... it is difficult to jet for.   Also, you actually get less power from a straight pipe.

You get get less back pressure with a straight pipe, unless you do something something like a chambered exhaust like they did on older muscle cars. It also sounds horrible, IMO.

That's good.  Have you considered rejetting? Getting the right mixture will give it a more steady climb all the way through the throttle range, will clear up the popping, and your bike will run cooler.
