Review & Install Video
Construction. Flowmaster's Force II exhaust system mounts behind the rear axle, utilizing factory mountings for easy installation. Tubing is fashioned from tough, 16 gauge, 409 stainless steel with a 2.5 inch diameter and 3 inch tip for strong, efficient exhaust flow. This axle-back system includes Mandrel bends to avoid exhaust restriction, and the system is finished in a black, heat resistant coating. This system is made in the USA.
The Force II is designed for Jeepers who want maximum performance combined with a quiet, conservative exhaust note. The sound level is mild inside the vehicle. Throttle response is boosted, and your Wrangler will get more miles per gallon while producing more horsepower and torque.
Application. Flowmaster backs this system with a limited lifetime warranty. This system fits 2007-2018 JK Wranglers, both 2-door and 4-door models.

Review from Flowmaster Force II Stainless Steel Axle-Back Exhaust (12-18 Wrangler JK)
New Exhaust
We really enjoy this new exhaust system, its not to loud and over bearing and looks a lot better than factory. It took approx two hours to install, just because it was hard to get the old exhaust off.

Review from Flowmaster Force II Stainless Steel Axle-Back Exhaust (12-18 Wrangler JK)
A little louder than expected...
I have had Flowmaster products on Mustangs for years so I know they tend to be loud. I guess the Mustang has more sound deadening material than the Jeep so I was a bit surprised at the interior cabin noise. Along with the KandN cold air kit, this does slightly improve performance and the dual exhaust looks great on the Wrangler. Sound is good.... but loud. Hardest part of install was removing the stock muffler which I finally had to cut the support arms to remove and then wiggle the muffler off the exhaust pipe as it was rusted. Once it came off, I had the new muffler installed in 5 minutes. Total time was roughly 1 hour.

Review from Flowmaster Force II Stainless Steel Axle-Back Exhaust (12-18 Wrangler JK)
Looks awesome
I had a hard time removing stock muffler so I took it to a shop and I was in and out in less than 30 minuets. I had them weld the Flowmaster on as the clamp I was sent was too big. I preferred the welding anyway. Looks and sounds awesome. Happy with my purchase!

Review from Flowmaster Force II Stainless Steel Axle-Back Exhaust (12-18 Wrangler JK)
More than I expected.
Being around a mechanic all of my life (father) I am a bit of a greaser my self. I was a bit skeptic at first from the reviews mentioning it's more like an import rocket. But combined with K and N intake and JMS pedalmax I am more than happy with the results. The sound is a nice almost V8 loudness. Did not take long at all to install this, I didn't even use a jack. HIGHLY RECOMMEND! And the heads turn when they hear me coming....

Review from Flowmaster Force II Stainless Steel Axle-Back Exhaust (12-18 Wrangler JK)
Mad bumble bee!
From the minute you start the vehicle you will realize this sound should be on a Honda Civic in the fast and furious movies. Why would anyone want an obnoxious rumble in the woods. Sounds great when standing behind the vehicle while idleing. Reminds me of my 1974 Camaro LT. But once inside and you accelerate it sounds like a vehicle that needs a muffler badly.

Review from Flowmaster Force II Stainless Steel Axle-Back Exhaust (07-11 Wrangler JK)
Big improvement
Easy to install once you get the old exhaust off, hardest part is getting it off of the rubber hangers, so use plenty of penetrating oil. Sound is great compared to the stock muffler.

Exhaust note
The tone has a great rumble at low RPM (under 3 M) Over 3M RPM it gets distorted The Down shift is about the same scenario

Good sounding muffler.
Fits well, sounds good. It was easy to install. I was able to remove stock muffler and install this one in the driveway. No lift needed.
