Bold Exhaust Tone. Give your Super Duty truck an exhaust tone to match its rugged good looks with the Flowmaster Force II Side/Rear Exit Dual Exhaust System. This cat-back exhaust transforms your standard truck sound to a bold, guttural exhaust note that will turn heads, but still remain manageable. In fact, this system produces an exhaust tone that manages to be relatively quiet inside your cab, making your drives more relaxing.
Enhanced Performance. The Flowmaster Force II Side/Rear Exit Dual Exhaust System employs a free-flowing design that allows exhaust gases to exit your truck faster compared to stock. This minimizes back pressure, resulting in better performance numbers. With this extra power on tap, you can take on more involved off-road adventures with ease.
Sturdy Stainless Steel Construction. The Flowmaster Force II Side/Rear Exit Dual Exhaust System features a 409 stainless steel construction for maximum corrosion resistance and strength. Each of the different tubing is mandrel-bent for rigidity, and feature fully-welded joints. Additionally, this cat-back includes 2 end-tubes – 1 for a split side, and another for a split rear exit. This allows you to customize this cat back according to your taste.
Easy Installation. The Flowmaster Force II Side/Rear Exit Dual Exhaust System installs on preexisting locations on your truck. You may need to perform some cutting to enable faster installation. Otherwise, installing this exhaust system is a relatively easy procedure.
Application. The Flowmaster Force II Side/Rear Exit Dual Exhaust System fits all 2017-2022 Ford F-250 6.2L Super Duty models.

Flowmaster exhaust
Good quality stainless cat back exhaust system. Able to install by one person, lift or cutting tools are helpful to remove stock exhaust. Sounds good.

NEEDS DEEPER RUMBLE
Looks good, nice exhaust bell/tips. Installation was a small hassel. While the stock exhaust has the flexible angle to compensate hanging and innaccuracies, the FlowMaster does not. What this means is, when hanging the pipe and atraching to the Cat section, the hanger wants to pull the exhaust to for to the driver side of the truck (2-3 cm, yes especially after going back to align and tighten down). This misalignes the flare junction of the Lead and Cat pipes. Ended up having to tighten down Cat-Lead, THEN at r aching the hanger to the rubberized islet, just barely into it mind ypu, or else there is way-too much pull on pipe. ALSO, this Lead-pipe hanger was too narrow to slip onto 3 in Lead pipe without tap tap tap tap bang tap down pipe with rubber mallet. The pipes hang ok. The other hanger on passenger side seemed to be JUST within the islet, not through...sighhhh. the red double rubber hanger holding the driver side has too much play. BuT pipes seem secure after several anal adjustments. The driver pipe is slightly askew, becuase of the bumber steel fram loops, the exhaust tips cannot get any closer than a few centimeters. Drone is almost non existent in idle or 10 gear. The sound...... siiiiighhh....a little better than a hopped-up V6 Honda. Performance.....I think with a turbo the improvements are almost non detectable. **If I could do it again, I could have opted to ONLY switch out stock muffler with the short FlowMaster Outlaw; which utilizes the stock resonater on the lead pipe...and is a much easier switch out. No, you won't get dual pipes but...I think , a more deep "muscular" rumble like a V8.

Fits well and sounds amazing.
I was concerned when I bought a different system. It couldn't be put on correctly. This one fits perfectly and sounds deep and throaty.

Exhaust installation
Fits like it was OEM, installed in about three hours working from a creeper. I recommend getting a new clamp for the cat connection before you start, the bolt on mine was rusted badly and I couldn’t get a wrench on it, so about 45min of install time was running to get a new clamp (Advance Auto # 36522)

Flowmaster Force ll dual exhaust
Exactly what I was looking for, nice deep tone but hardly noticeable in the cab. Definitely louder than stock, but won’t wake the neighbors at cold start. It took about 2-2-1/2 hours to install, that includes taking the old exhaust off without a lift

Love my Flowmaster duals
Nice kit, eveything fits nice. The hardest part was removing stock exhaust, had a rusted clamp had to saw off and replace ( just happens it's the one I was to reuse}. Took me by myself about 2hrs to install.

Flowmaster force 2
Great choice for the silverado. Was honestly harder getting the old exhaust off than it was putting the new on. Perfect fit. Nice rumble. Definetly louder than stock, but not wake the neighbors. I chose this one for the 50 series muffler. There is no resonance issues on the highway when the cylinders drop.
