Flowmaster 817729 12-18 Jeep Wrangler Jk 3.6L Fii Axle-Back Exhaust System Dor 4, Black

Put Flowmaster on my 2018 Jeep JK. Looks & sounds great! Not too loud but gives the 6 cylinder a little rumble.

EZ install in about 45 minutes. Best sound for a 6 cylinder Jeep. Mellow sound at idle, Comes alive when accelerating, then all's quiet when up to speed. I seemed to have gained a couple MPG (City) with this muffler.

The dual chrome tips look outstanding under the rear bumper.Not too loud; but a nice growl (for a v6) when you get on it a little bit!

If I was going to purchase this again, I might go for the single-exit Flowmaster Force II instead. The dual-exhaust tips aren't quite symmetrical on my Jeep, but they don't look too bad. I suppose it might be possible to bend the hangers to get them more even, but I don't think it's something I want to mess with. I am very satisfied with the sound -- louder but not too loud. I would feel more secure if the kit also supplied a hanger keeper for the right side. I installed this in an afternoon with no prior experience; the most difficult part was pulling the old muffler loose from the rest of the exhaust. I'm sure exhaust removal pliers made the job much easier. Installing the hanger keeper was also a little tricky; I finally succeeded by pushing it on with a socket from my socket wrench set.

Used a Flowmaster on my 2010 Sahara and it was fantastic! Now that I have a new 2015 Rubicon I ordered the Force II. It was installed and it sounds even better. Good throaty sound, like a growl. Opted for the dual tipped exhaust this time. Looks and sounds great. I get 22 MPG now out of my Rubi.

Love the sound and the look. Sets my 2016 Jeep Wrangler apart. Easy install, but I paid a muffler shop $80, and it took him about 25 minutes. And my Jeep was brand new!

Easy install, looks great, sounds betterDoesn't give any extra hp tho

Slightly increases power, great sound, and modestly improved gas mileage. Wish I had purchased a Flowmaster for my prior 2007 Wrangler years ago.
