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 2021-2023 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.

Why Drivers Choose FAST of West Chester

I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
support my builds going forward.

Donald Wojnar
I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

Adam Cranston
The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

Bryce Budd
This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

William Brunell
Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
and what I needed to get where I want to be with it. I'd recommend them
to any car enthusiast.
