        5 2017 Rubicon - i3onzai Installation Time: Afternoon

        Great Exhaust

        Showed up on time with no damage to the packaging! Installed on 2017 JKUR. Removing factory exhaust was the hardest. I ended up using a saw to cut the pipe out in easy to maneuver chunks, and a cut off wheel to slice the nipple of the exhaust hangers and pull them out. Install on the Magnaflow was really nice. Everything fit just right and had all the correct hardware. After all said and done, there are no rattles, plenty of clearance around everything, and the sound is awesome. Nice low rumble at idle and while on the trails. Gets good and noisy when you put the hammer down getting on the highway, or passing. Clearance wheeling is great also. Flexed out on the rocks there was plenty of clearance for suspension. Thumbs up

        This exhaust rocks!

        Installed the Magnaflow Rock Crawler Cat-Back Exhaust two weeks ago and couldn't be happier. The install was easy and the sound is fantastic. If you are looking for something with a little more rumble, but not too loud, this is the ticket. Fairly quiet at idle and at cruising speeds. Nice sound when on throttle. I can also feel a tangible performance improvement at higher RPMs. Exactly what I was looking for in an exhaust system.

        Great exhaust

        Bolted on easy, I recommend using torch gun to make it real tight. Great sound, it’s not too loud. Much more clearance on the back end. Great product.

        Big difference..

        I am glad I chose this exhaust after looking at several types and brands. Not the cheapest, or most expensive system but it was worth the cost and wait. I notice a huge difference in horsepower and the nice low sound is a definite improvement over the cheaper competitors rear exhaust that I had . Professionally installed and an Awesome Mod!

        5 2018 Wrangler - emjman18 Installation Time: Afternoon

        Nice exhaust

        First things first, hit ALL of your rubber hangers with bb blaster or wd40 before attempting to remove your old system. It took me 2 hours to remove it bc i didn't do that step. The new exhaust went on in less than 20 minutes, very nice clamps and easy to install piping. After a few heat cycles it got a louder, crackles and pops a little bit between shifts or when going into neutral. Doesnt drone untill you hit 3k rpm, not bad on the highway at all. Feels like the engine breathes a lot better with this pipe and with a cold air intake. Jeep whips doughnuts in the dry now

        Awesome

        I love the sound. Really changed the way my Jeep sounds and looks honesty. Cold starts are amazing now. Install took me 5 minutes once I took my old system off. Packaging was solid as well. Use lots of WD-40

        Rock crawler magnaflow for jku

        I recently lured on the rock crawler magnaflow wotj no additional performance parts and I've noticed a gain in throttle response and top end speed as well as better fuel mileage . I was getting 17l per 100 km and now I'm down to 15.5. Great purchase.

When I was old enough to drive I bought a Cherokee and went through 3 of them before deciding I wanted a Wrangler. So I sold my Cherokee and sat o...
