Definitely a drone on mine. And I'm saying that having had aftermarket exhausts on all cars I've owned (some quite loud). But big difference between more sound from an exhaust and drone - this is pretty bad and borderline intolerable. Hoping it disappears when I slap the MadDad midpipe.
Anybody here running an aftermarket midpipe on an otherwise stock setup that can comment how that affected the drone? TIA
