MagnaFlow Cat-Back 2021 Jeep Wrangler 6.4L Rock Crawler Series Dual Exit Stainless Exhaust

The MagnaFlow® Jeep Wrangler Rubicon 392 Rock Crawler Series™ Cat-Back Exhaust System #19582 is tuned to upgrade your rig with MagnaFlow®’s deep exhaust note and dyno-proven performance gains. Exhaust kit #19582 is designed to make your Jeep Wrangler Rubicon 392’s 6.4L HEMI V8 produce an even more aggressive exterior sound while keeping things to a moderate level within the vehicle’s interior. This, combined with the use of a MagnaFlow® NDT (No Drone Technology) Resonator to eliminate droning noises at cruising speeds, improves comfort on long drives. The mandrel bent 3” main piping and straight-through muffler bodies of this Jeep Wrangler Rubicon 392 exhaust system are secured using the included racing-bred v-band clamps, with exhaust gases vacating through a dual high-clearance exit that offers improved departure angles for those times when you decide to leave the road behind and test your SUV’s capabilities. Corrosion resistant stainless-steel construction and CNC precision manufacturing ensure superior durability and reliable performance. #19582 is backed by MagnaFlow®’s limited lifetime warranty.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
