Just a little info on the mufflex kit. It sounds great at startup, at idle, and when running down the road. Love the sound makes it sound like a hemi should. The bad: if ya tow a lot the drone will kill you. It drones a bit when on the highway empty between 1500-1800rpm but it's liveable. But any load or trailer towing it's pretty bad. Just my two cents for anyone considering it. I'm back to stock muffler with the butterfly knocked out and the resonator removed.

had my mufflex Maggie for 20,000 miles + now. still same drone as when new, no improvement. But I don't have an intake kit. I'm still holding my breath and waiting for Corsa to put out a cat back. Not ****** likely though.

I'm thinking of an electric cutout so that when I feel like making some noise I can but I can keep it nice for towing. When I took off the resonator I welded the tailpipe back together n kept it tucked up so ya can't see it.

I would think with the 6.4L you'd get more drone than the 5.7L.
Having a dual output pointing straight at your tow load can't help.
I'm thinking turn-down tips might be a reasonable investment if you tow a lot and have one of the rear bumper dual exhaust models.
The wife has been talking about getting a camper, but that would probably mean I'd upgrade to a used 2500 with CTD if I can find one--especially if we go fifth wheel.

Never saw a 6.4 with the dual exit exhaust unless someone changed it over I think they all come with the single tailpipe with the ugly resonator.
