      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.
