The MagnaFlow Jeep Wrangler JK Overland Series Axle-Back Performance Exhaust System #19668 is engineered for off-road function and built to explore further. This Jeep Wrangler exhaust system is designed for the 2007-2018 Jeep Wrangler equipped with the V6 3.6L or 3.8L engine option. The high clearance exhaust design of this kit is designed to keep clear of any challenging terrain or obstacles you may come across. #19668 2.5” diameter mandrel bent main piping passes through an 18” straight-through oval muffler and No Drone Technology (NDT) tuned chamber before exiting in a high-clearance tucked tailpipe to the rear of the passenger side. MagnaFlow NDT utilizes passive quarter-wave noise cancellation to minimize the unwanted droning noises that can otherwise occur at highway cruising speeds. The entire Jeep exhaust kit can be tailored to your preferred exhaust tone by changing out which module is attached to the integrated mufflerâ€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 exhaust sound profile you choose to go with is up to your driving style. 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 #19668 utilizes a direct-fit easy to install design that replaces your OEM exhaust system from near the rear axle on back. This Jeep Wrangler JK axle-back performance exhaust system is made of durable corrosion resistant stainless steel and produced using advanced CNC precision robotic manufacturing techniques all backed by MagnaFlowâ€s limited lifetime warranty.
