I ran the Roush AB setup on my 2014 for 5+ years and loved it but the drone eventually got to me. I switched to the GT500s and they were nice with no drone but felt a little too quiet/tame…so I added LTH over the axle pipes and it’s about perfect now, IMO. It’s aggressive and still has some snap, crackle, pop but not too much drone and is not as loud as the Roush setup.
