If it really starts to bug you and you have the adapters to mate the rear section to a stock style midpipe, get a set of Turner (or the recent clones) test pipes. Power difference is pretty small and you'll end up with heavier gauge stainless steel tubing. I found it to be a quieter solution at low rpms than the full Evolution system. Very similar from a tone perspective - less hollow sounding in the car.
