There's always a lot of folks asking exhaust questions about the 6.4 so I figured I'd chime in with what I've had and experienced on my truck.
Exhaust note and drone are pretty subjective but my personal preference is I want little to no drone as I tow and a low rumble outside the truck which wakes up when you get on it. I like the noise outside the truck not bouncing around the cab. I do a lot of city driving which leads to some lugging at times which makes the drone worse than if you're doing mostly highway driving. I want just a bit more sound than stock provides.
The exhausts:
1) Stock - We all know what this one sounds like and that is has the flapper valve.
2) Mufflex Magnaflow with stock resonator - A deeper tone than stock and a fair bit louder outside the truck. Has a noticeable though not overpowering drone from 1500 - 1800 rpm (my truck has 4.10s) when the engine might be lugging a bit. You will hear it inside the truck whenever you get on it. Once you get up to 120 KM/H or so cruising on the highway you barely know it's there. Was OK towing a 7200lb travel trailer as well. Didn't mind it but thought I'd try something else to try to drop the drone a bit. Got a little better mileage than stock with this one too (1.5 - 2.0 L/100km better than stock via lie-o-meter).
3) Flowmaster American Thunder #817709 Cat Back Kit- As I was laying down the plastic for this one (impulse buy - they had one in stock) I was thinking maybe I was making a mistake. For my tastes, I should've listened to my gut. Sounded really kickass on the Flowmaster site so I took the chance but I admit I've never had a chambered exhaust before. The kit is really well made and went in nicely, even the hanger for the driver side tailpipe worked well. Sounds great outside the truck (idle is maybe just a touch louder than the Mufflex unit) and when up to speed cruising on the highway you can hear it's there, a bit louder than the Mufflex when cruising, and I'd call it a deep rumble. Sounds really good. I might've kept it if I was doing mostly highway driving. For my tastes, it had a heavy drone at about 1500 rpm in city 'stop and go'. I had my shop weld in a 12" resonator before the muffler and it helped a lot with the drone but still too much for me so it came off. I was manually shifting the truck to get it out of the 1500 rpm range which is a pain in the ass. If you don't mind loud drone inside the truck while city driving this will work well for you. The Flowmaster website calls this exhaust 'Moderate' sounding and then in the description mentions it perfect for people who like an 'Aggressive' tone inside and outside the truck. I would lean more towards aggressive than moderate if I was describing it. If you floor it merging onto the freeway it will bring a smile to your face though. Back when I was 25 - 30, this would be my exhaust or if I was driving almost exclusively highway miles it would be a possibility. Never towed with it so I can't comment there. Didn't have it on long but saw about a 2.0 L/100km decrease from stock via the lie-o-meter.
4) Magnaflow #12909 with the stock resonator - After I pulled the Flowmaster I went back to stock for about a month and then picked up one of these. Left the resonator in place as it obviously manages the drone well. This muffler is 22" compared to the stocker 28" and is 3.5" inlet and outlet. It's not a bolt in like the Mufflex Magnaflow but any good shop with 3.5" pipe will set you up. Just a touch louder than stock inside the cab with no drone. Outside the truck sounds like the Mufflex Magnaflow if you reduced the volume by about 1/3. If you get on it, it sounds good, definitely a deeper rumble than stock provides but nowhere near the roar the Flowmaster will crank out. I will be keeping this one on there as it's the best compromise for me. Hoping the straight-through design of the muffler will get me some better mileage as well after the winter-blend gas disappears.
Again guys, exhausts are pretty subjective but hopefully this might help somebody before they drop a ton of dough on something they won't like.
Bottom line is you'll never know if you're going to like it 'till you drop the cash and put it on. YouTube videos may or may not tell the tale.
But damn, that Flowmaster sure sounded good on the truck and on YouTube....oh well, live and learn.
