The MagnaFlow Jeep Wrangler Overland Series Axle-Back Performance Exhaust System #19620 brings additional off-roading prowess, dyno-proven performance and a tunable exhaust sound to your 2018-2023 Jeep Wrangler JL equipped with the 2.0L or 3.6L engine option. The high clearance design of this exhaust system is designed to keep clear of any challenging terrain you may come across. #19620's 2.5" diameter mandrel bent main piping passes through an 18" straight-through oval muffler and NDT (No Drone Technology) tuned chamber before terminating in a high-clearance tucked tailpipe to the rear of the passenger side. No Drone Technology utilizes passive quarter-wave noise cancellation to minimize the unwanted droning noises that can otherwise occur at highway cruising speeds. The entire kit can be tailored to your preferred exhaust tone by changing out which module is attached to the integrated muffler's accessory port. The included pipe cap, J-pipe and NDT modules can be combined in various ways to mitigate a wide range of droning frequencies, so which sound profile you choose to go with is up to you. Because the integrated overland muffler incorporates NDT technology to begin with, all configurations offer various forms of NDT benefits. Looking to minimize overall drone? Simply connect the NDT module. Prefer a more traditional rendition of that famous MagnaFlow exhaust tone? All you need to do is cover the accessory port with the included pipe cap. Exhaust kit #19620 utilizes a direct-fit, easy to install design that replaces your OEM exhaust system from near the rear axle on back. This Jeep Wrangler performance exhaust system is made of durable, corrosion resistant stainless steel and produced using advanced CNC precision robotic manufacturing techniques, all backed by MagnaFlow's limited lifetime warranty.
