[MENTION=22171]BlackScab[/MENTION]. It would certainty be expensive to ditch your new system over drone issues. You sound happy with the quality and exhaust note in general. Is it possible that the "true dual" exhaust systems are identical so they harmonize with each other at certain RPMs? Maybe Magnaflow overlooked this. Just a thought. Maybe have your exhaust guy weld in two Hemholtz resonators. There's a thread on that here but I was unable to find it. Hope it works out.
