2020 Lone Star - Chris89
Sounds Great
I was wanting an exhaust that complements the look of my 2020 Ram 6.4 2500 and this matched the look and sound I was going for. I installed it after work took me a little over a hour. The longest part was removing old exhaust. I would recommend to anyone wanting a better sound and look like a HEMI should.

Flowmaster flowfx dual exhaust
Love the sound and looks awesome. Install was easy. Only had 1 hickup which was the tips. I could get 1 of the tips to tighten up all the way. Ended up popping a tab, so i tac welded tab and fixed the problem

2024 Power Wagon - JSexton
Perfect sound for me. Flowmaster QA is trash.
Ram 2024 tradesman 2500 with powerwagon package aka poverty wagon Does it sound wonderful? Yes, absolutely. Does it look nice. Yes, absolutely. Does it fit well(not hit anything during axle flex, so far no) The pipes were full of metal shavings. And the grade 1or2 Corrosion film they applied was a little frustrating considering the shavings. BRING YOUR PB BLASTER. YES it's sticky and yes they all stuck to it. Did the pipes fit together well? Absolutely not. Were there unfinished edges all over the darn pipe ends and hangers? YES AGAIN. Good thing i am a mechanic otherwise my hands would be shredded (gloves are for sports) The fitment was definitely not wonderful. Use a cheap deadblow cause you will shred it on the sharp edges. I also ended up cutting the pipe that goes over rear axle (2 1/2) inches and boy that made all the damn difference in mounting/ hanging securely. The first pipe(from the Y) has an unusable hangar. There's no factory mount for it. Overall it works and sounds great. Doesn't hit anything thus far( about 2 inches from right passenger spring). Tip is flush with body right now. May move it out an inch or so if the exhaust is effecting the paint. But I doubt it will. Anyway. DONT BUY THIS IF YOURE DOING THE JOB FROM HOME and or expect to be easy. It's work. Not terrible but unexpected work is never fun. Flowmaster.. shame! Do better. And yes I still love you.

Liking the Flow!
Great sound and notice a few miles per gallon increase. I do feel the horses got released and not too loud and very enjoyable for those like me who like the hemi roaring!! Took me some time to get the OEM pipes out due to some fixed pins on the connection to manifolds but installing the Flowmaster was done in 30 minutes. Recommend this product!

Easy install / Fit perfect
This exhaust fit well and looks and sounds really good. I did have to cut back / alter small 90 degree tail bend pieces, but wasn't a big deal
