Well I installed the 14" Magnaflow from B2Fabrications. Initial impression:
Install: Very easy, about 1hr. A recip saw vs using a hack saw could have saved me about 10 min. (see tip at bottom for easy fitment)
-Interstate speed-no real in cab sound, hardly tell the difference from stock with the radio off.
-Moderate acceleration-In cab sound is louder than my 2012 possibly due to the old truck was quad cab vs crew cab on the new truck. Still the radio at medium volume easily covers it.
-Heavy acceleration-Not really any louder than moderate acceleration just more aggressive sounding. You definitely know you have done the exhaust.
-Idle-On cold start I'd say it is louder than the 2012 but once the truck is warmed up the sound difference is not much over stock. You have to be standing right next to it to hear it idle when warm. When I cold start in the A.M. with remote start I can hear it fire up and idle in the house.
Overall, I think it will be similar to the DOD14 that was on my 2012 once it fully breaks in. If you want a moderate exhaust that doesn't wake the neighbors but still sounds a little throaty with zero drone this is probably a good buy. As for me I almost regret not going with the Pypes (next step up) or the muffler delete. For $185 I might try the delete for fun.
Tip if you do buy this or something similar. When you are fitting up the new exhaust to the coupler apply the high heat permatex or similar, fit up the tail pipe portion to the new exhaust. Snug it all up by putting a ratchet strap around the Y portion where the dual exhaust splits off and the frame forward from that point. A couple of clicks and ever thing come together very well, really saves you from trying to force the exhaust into the coupler.
**side note** When I took the exhaust off my 2012 before installing the new exhaust I started it up for fun. It was ridiculous, rattle your windows, send women & children running, scare your neighbors dog LOUD! A single 4" dumping out under the cab I was like a kid in a candy store just had to go drive it around for an hour or so before neutering it.
As for the 2019 I fired it up in the driveway after removing the exhaust and it was not even close to as loud with no exhaust and brought no such joy.
Sorry for the long read.
