Went for the rpi gts and really enjoying it. Still getting to know the exhaust, but I agree, no drone during cruising but does have some resonance at lower rpms, but definitely less than the other options. I think if anyone is looking for that subtle increase over stock but still wanting a noticeably aggressive and louder sound, the rpi is an awesome choice. Great fitment and hoping those dynos are correct. Wished the stock came out like this. Thanks for all the feedback!
