    Review & Installation Video

    Review & Install Video

    Deep Rumbling Exhaust Voice. Upgrade your stock exhaust sound with an attractive, deeper rumbling tone from a Magnaflow MF Series Axle-Back Exhaust with Black Tips. This axle-back exhaust kit passed the SAE J1169 Standard for exhaust sound level, which means this modification is perfectly street-legal for your 2018 3.6L Jeep Wrangler JL.

    Better than OEM Performance. This axle-back exhaust kit features a free-flowing, straight through muffler design, a highly improved version of your OEM part. It makes for a more efficient exhaust system that results in horsepower and torque gains.

    Top-Notch Construction. Like all Magnaflow products, the MF Series Axle-Back Exhaust is built to last. The components from mufflers to dual tips are made of 409-grade stainless steel, an alloy known for high-temperature and corrosion resistance. Add to that, the attractive black satin coating that not just looks sleek on your Jeep; it also reinforces the protection against rust and corrosion.

    Clamp-On Installation. The Magnaflow MF Series Axle-Back Exhaust is easy to install, as it’s a direct replacement of your mufflers and tips. Although a new clamp is provided, you will need to save the existing hanger to reuse on your new muffler.

    Magnaflow’s Comprehensive Warranty. Magnaflow shows their commitment to quality auto parts and customer satisfaction by providing a lifetime construction warranty to cover structural damages occurring under normal use. As if that’s not enough, they are also including a separate 1-year warranty to cover defects on its beautiful black satin finish.

    Application. The Magnaflow MF Series Axle-Back Exhaust with Black Tips fits 2018 3.6L Jeep Wrangler JL models.

    3 Top Rated Questions

    According to first review. Diameter of the Magnaflow pipe and stock JL pipe are the same??

    • Yes the JL and this exhaust kit does have the same piping diameter this is very common with aftermarket exhaust. Allowing a tight secure connection when installing the axle back onto the wrangler.

    My new JL 4 door Wrangler Sahara has the new 2.0 liter i4 Turbo engine, will this work on mine? What benefits will I gain from this mod, or what will I lose?

    • We have only confirmed fitment with the 2018 3.6L Jeep Wrangler JL's at this point in time.

      Great exhaust... Had to weld it on

      To me it seemed like it took some time for the exhaust to "break in" and really get loud, but it sounds great. The only problem was that it didn't fit so I had to weld it on... Took about 10-15 minutes to install

      15 Minute Install

      This was ridiculously easy to install, I didn't have to lift the JLUS, and I did it myself in 15 minutes or 1 cold beer... however you look at it. I figured I would get that out of the way at the beginning, with everyone saying that it was difficult. The JL is my 6th Jeep and 4th self install of exhaust, watch the video, get your tools ready, and get to work. The only recommendation I can make on the install is spray a little wd-40 dry lube when you're sliding the pipe on and it will glide into place easily, then clamp it down. I did opt to go the route of removing the exhaust hangers with the stock exhaust and remounting those after swapping them to the new exhaust, brilliantly easy with the dry lube. The top tips of the pipes sit about an inch below the stock JLUS bumper and do not stick out at all, maybe 1/2 inch inside, allowing you to not lose much of your rear attack angle. Let's move onto the sound and performance. I absolutely love the sound coming out it, at idle you can barely tell you have an aftermarket exhaust and when you're just rolling off you can really get a deep purr. I have the auto/8-speed tranny and there have been a few occasions in my neighborhood at 25MPH where the exhaust produces a loud drone that turns my neighbors heads. Speaking of drone, in my setup(JLUS 8-speed auto), cruising at 50-55 does create a drone that is noticeable when the sunrider soft top is all the way down and doors off. Other than that, I love the tone this things puts out. It's not gawd awful loud like my cousins 2000 chevy with flows. I think they hit the perfect pitch that allows our 3.6s to grow some cojones. Performance, negligible. Maybe it does, maybe it doesn't, I'm not even gonna test that. What I have noticed is that my miles per smile has gone from 23 to a solid 20 because i'm romping the throttle now that I have this installed, I can't imagine what's gonna happen when I save enough money for a lift and wheels! :) Hopefully I have given you some solid feedback and I really do hope if you buy this, you are able to easily install it. Maybe I ended up with a newer setup from MF with adjusted fitment. Good luck to you all! -Zac

      Wow just wow - terrible!

      Expect significant installation problems - the fitment is so far off it takes an exhaust expander to get it on. They obviously know they have an issue (as evidenced by other reviews).

      Don't Buy

      The finish is good. Unfortunately early production has fitment issues as per previous reviews. I thought by now ET would have the exhaust that fit the OEM tailpipe. I spent 2 hours trying to get the exhaust on my 2018 JLUR. It will be sent back tomorrow. I am done with ET.

      Sounds great!

      Like the other reviews it is a tough fit, it was going to be impossible to get it all the way on without flairring the end. Luckily my friend knew someone at the muffler shop and he flairred the end in 2 seconds and it slipped right on. But looks great and sounds awesome..

      Does not fit

      Unlike the factory exhaust which slides on and off super easy, this just doesn't go on. I fought with this thing for over an hour trying to get it on and no luck. When I went to put the factory exhaust back on it literally took me 2 minutes. Clearly from the other reviews it doesn't fit. There should not be a need to take it to a shop. Beware.

      Tight fit, tough install

      I agree with Jeffrey B. this is a tight fit. I installed the MF axle back exhaust on my 2017 JK, and that installation was much easier. With everything I've found so far with JL, things are different and more difficult than with JK. This is one example of the difficulty. It's very tight and snug, and requires many whacks with a rubber mallet hammer to get it to in all the way and then clamp for extra support. It took me about 1.5 hours and a lot of swearing and sweating and banging with a mallet to get it to move 1 centimeter each hit. Ends up looking amazing, sounding amazing, and is worth the installation troubles. Also, when I removed the stock exhaust muffler from my JL, the clamp was welded on. With my JK it was NOT welded on, and I was able to use the clamp. Make sure you find the clamp in the box with yours, mine was missing and I had to pick one up at an auto parts store. Good luck, it's a tight fit, but worth the effort!

      Fits Perfect, Looks Great, Sounds Amazing

      I’m not sure what JefferyB did wrong but mine fit like a glove and only took 20 minuets to install and that includes removing the factory muffler. The MagnaFlow 19388 fit about 3” over the existing tailpipe and married up to the stop that is welded on the tailpipe. The twin exhaust pipes are perfectly even under the bumper and look outstanding. The sound has a gorgeous lower tone and is not loud. At 3,000 RPM it sounds like a finely tuned muscle car. I am very happy with this product from MagnaFlow.

      Does not fit JL

      very frustrating. ordered for Rubicon JL. diameter of stock pipe and magna flow pipe are the same. would not fit over. tried to widen but only able to get it fit inch and half on. Had to weld it on ! even if it did fit and was slid all the way on would have left exhaust tips behind rear bumper by about three inches - not good
