    Best muffler yet

    I love how the muffler sounds, I didn’t even try to do it my self I took it to the muffler shop and within 20 mins I had my flow master done. Sound is amazing I read a lot of reviews saying that it will sound like a civic and this is not the case.

    Just right

    Simply put this has the right amount of sound for a Wrangler. Not too much, not to little. Super easy install.

    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 Jeep 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.

    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 Jeep 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....

    Installing exhaust

    It was a easy install but had trouble with how the tips extended at the bumper , one stuck out further than the other.

    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.

    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.
