Too much drone
This system came recommended by 2 local shops as a quality inexpensive replacement to old factory system without drone. In the month I've had it, I've spent a lot of time tweaking to try to reduce the 2k rpm half throttle drone without any real luck. Full throttle sounds good and cruising at 70 is in the sweet spot but accelerating at part throttle through about 2000 rpm yields a lot of unenjoyable drone in the cab and no real redeeming performance exhaust note. Very easy install. Looks nice.
