Unlock some Power. This moderately louder Magnaflow Rockcrawler Exhaust from Magnaflow is a great way to wake up your Wrangler's performance and sound. A single high-flow, straight-through muffler increases outflow dramatically, letting your engine breathe better and provide better performance.
Unleash More Noise. The Magnaflow Rockcrawler Exhaust is a more aggressive cat-back, featuring a straight-through Magnaflow muffler with a perforated core. This core helps reduce interior cabin drone and hones the exhaust notes to avoid raspy, empty tones in the higher end of the power band.
Mandrel-Bent Steel. The Magnaflow Rockcrawler is as tough as it sounds, featuring quality stainless steel 2.5" tubing that's mandrel-bent to precision specs, making for a simple installation and perfect fit. This precision construction keeps the whole kit close to the body to ensure high clearance for off-road use.
Bolt-on Installation. The Magnaflow Rockcrawler Cat-Back Exhaust is a bolt-on installation, utilizing the provided clamps without the need for cutting, welding, or custom fabrication.
Application. This Magnaflow Rockcrawler Cat-Back Exhaust fits 2007-2011 JK Wrangler 4-door models.

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 upHelpful (2)

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.Helpful (1)

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.Helpful (1)

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!Helpful (3)

Pretty easy to install with a great sound. Not too loud till you put the peddle down, but you can definitely hear the notes.Helpful (1)

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 nowHelpful (1)

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-40Helpful (2)

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.Helpful (2)
Is this system made specifically for a 2-door model JK or will I still have to cut 20ish inches off like most of them?

How loud is it when Jeep is stripped down?
