Are you running stock cat? I noticed with my RV6 down pipe and front pipe it's much louder and often. I can pop in all lower gears, 4 and under when shifting around 3k rpm.

Yes but there not excessive. Your comparing a pop or 2 from the factory, compared to crackle tunes that just pop non stop while your decelerating. To get that constant constant pop that's endless your dumping unburnt fuel which in the long run will damage your catalytic converter. If your straight piped then great

Case in point, that was my first mod to the my M2C. Turned off the factory overrun which was very contrived and predictable. It was like a Jake brake on a semi. The factory tune (minus overrun) is much more satisfying, low grumbles off throttle and a single *bang* on aggressive upshift.
