MBRP Exhaust S5150AL on 6.4L

[Iampeter]

Anyone running the MBRP S5151AL exhaust on there 6.4 Hemi? How loud is it and how much drone in cab? I pull trailers almost daily and don’t want to drown out the Alpine stereo or conversations.
Thanks in advance for any feedback.

Did you ever get an answer elsewhere or decide on another cat back system?

I did MBRP cat back system on my 03 SLT the S5102AL . Loved the fit and finish. I had TTI longbtube stainless headers plugged into twin cats, high flow y pipe to 3 “ inlet piping to a single MPRP muffler (straight through design) with 3" outlet pipe to a 4” tip T5156 on passenger side exit at the rear quarter panel. Loved the sound around town, not to obnoxious at all. But sad to say at highway cruise speeds 100 to 115-120kph the drone was embarrassingly loud. Had to get it above 75mph or more before the harmonics began to taper off. Took it for a few years then replaced just the muffler with a Walker OEM replacement unit.
Truck was great on the highway after that. I did all this for fuel mileage but did not realize any gains I don’t think. Yeah, had a cold air kit on it to ducted to a SRT hood with plenum.
