Magnaflow 4x9 performance muffler
I decided to go with the magnaflow for a couple reasons. I was told they're more durable and last longer than other knock off brands being that its made from 409 stainless steel. Also the sound is aggressive but not too much that it drones all the time. Just when you get on the acceleration. Sounds great and from what i hear the sound most likely will get a little more intense after the muffler breaks-in period and fiberglass breaks down. The set up comes with clamps but I had the muffler welded to the exhaust pipe. Too many complain of loose hardware after driving a bit. You could upgrade the clamps but I'm happy with the way mine is set up being welded. No leaks or clanging. You could install yourself which i would estimate 1-90 minutes only because existing hardware will most likely be rusted. I had an expert do mine which cost $150 labor (including weld). So I definitely would recommend this muffler system. ??

Magnaflow for the win
Replaced a MBRP muffler on my ram. Thus maganflow was greatly built and sounds fantastic. A great rumble for the price.

Magnaflow Exhaust
Good sound but not too loud outside the truck. Is a little louder inside the cab than I expected when getting up to speed and shifting through the gears. Install was not bad at all but the two hours they say in the video is only accurate if the existing exhaust comes off flawlessly. Mine to me about 2 hours just to get the old exhaust off. I recommend getting a new clamp for the y-pipe and bolts for the y-pipe. My bolts broke off which is expected with older exhaust and the clamp was not reusable as well due to the age of it. The install of the new exhaust once the old was off was probably only 30 minutes.

Sounds great
Excellent exhaust, nice tone. Not loud, but loud enough (deep rumble) to turn heads, no drone sound. Took longer to take off old exhaust than to put new one on, 3 hrs complete.

5” magnaflow exhaust system
Super easy to install, took about an hour total. Looks great, but not much louder than stock, adds a little deeper rumble but that’s about it. I didn’t like that after the first day the tip yellowed but other than that, I’m satisfied.

Looks good, bot the sound i was hoping for.
This thing looks great! However, its really not much of a difference in sound. The dpf really hampers the low deep grumble i was hoping for. I do notice a slight pep in the overall performance with the truck when I step on the gas pedal.
