      Awesome upgrade on 2012 Wrangler JK

      I wanted a more aggressive tone to my exhaust without waking up the neighbors...it's a nice balance, and I love it!

      Review from Magnaflow Rock Crawler Cat-Back Exhaust (12-18 Jeep Wrangler JK 2 Door)

      pretty good

      Even though it sounds nothing compared to my 2011 camaro SS Borla exhaust, it does sound pretty good when rolling down the pavement or crawling over obstacles. I mainly got it though for the fact that it will be nearly impossible to damage it unless you pin yourself on a pointed rock at just the right spot because it gets rid of the back exhaust you see when looking at the jeep and locates it up in the frame. I will say, you will prolly have to cut off the old exhaust due to the front most clip faces upward from the factory and there is no way to physically get to the bolt to get it off. good luck

      Badass

      Good quality exhaust system, fits nice and snug under my JK. Awesome sound, not obnoxiously loud, even when you really give it some to talk about. Would reccomend to all JK owners.

      Amazing upgrade!

      Easy to install, took me about 45min to an hour definitely helped that I WD-40ed all bolts and rubber bushings ones a day for three days before attempting to install, the sounds ten times better!

      Great exhaust

      This is a pretty solid exhaust. Install is easy. Removing factory exhaust was difficult. I had a muffler delete for a while and this is a huge improvement. To understand how loud this is, remove the muffler from your jeep. It is probably 75 of mufflerless sound with significantly better tone and no freeway drone. Plus it won’t get smashed on rocks like stock.

      Magnaflow Rock Crawler Cat Back Exhaust

      Received it fairly fast giving that it came from California all the way to Ohio (5 days) and just had the time to install it today. Just as everyone says getting the old exhaust off was a major pain, about an hour, an adult beverage and a few choice words but nothing that grinder and a cut off wheel couldn't handle....... on to the install.....super easy, took about 20 minutes total and I really like the sound. Nothing ricey just a nice lower tone and on the highway it actually is pretty quiet. So overall I would highly recommend this Magnaflow exhaust to all JK owners

      Better than stock

      Install was easy although it doesn't quite fit correctly. keeping it straight and from rubbing was next to impossible. Need to get some rubber shims. The note sounds more like a car than a truck. I can see where people are comparing it to a "ricer" I don't think it is as bad as that. should deepen after it gets some miles on it. (Removing Stock exhaust is where you will spend most of your time. clamps are tac welded. lots of rust. 2012 )

      Bad Fit

      The exhaust did not fit properly on a 2017 JK 2 door. Two hanger points had to be cut then re-welded in order for the exhaust to fit. Without the re-welds, the exhaust resonator hit the frame and the exhaust tip hit the rear frame. Horrendous build quality. The install cost doubled due to the fitment issue.

      Bad system

      This exhaust system will not fit a 2015 JK without banging against the frame in 2 places. Very disappointed in Magnaflow for the design. I did replace it with a Magnaflow system with the muffler in the back. Cost me almost $500.00 for the screwed up system.

      Review from Magnaflow Rock Crawler Cat-Back Exhaust (07-11 Jeep Wrangler JK 2 Door)

      Good Exhaust for the right person

      This install took right around 3hrs. This exhaust cleans up the underneath and greatly increases the sound. Some might even say it is to loud for them. However I find it just right. The exhaust itself is very well made and the directions are very clear. The only reason this took me so long to install is due to 8 years of rust and corrosion. Make it easy on yourself and have a vehicle lift and a rotary cutter on hand along with air tools. Also you might want to consider on buying some heavy duty rubber to put between the frame rails since the exhuast lays against it to reduce noise vibration. Other than that this exhaust is fantastic and highly recommend it.
