2012-2018 Jeep Wrangler JK MagnaFlow Loop Delete Pipe

Jeep Wranglers are one of the few vehicles that have a stock loop section equipped on its exhaust, and while this may work fine for basic everyday applications, the loop section can interfere with aftermarket upgrades and even slow down engine performance along the way.

MagnaFlow understands that this isn't always the best setup for every Jeep build, which is exactly why they created the 2012-2018 Jeep Wrangler JK MagnaFlow Loop Delete Manifold Pipe. Also known as a performance manifold pipe, the loop delete pipe replaces the restrictive factory loop with a straighter, free-flowing design to improve airflow, engine efficiency, and overall performance. Each pipe is weight-optimized for maximum flow and helps your Jeep generate more power—ideal for off-road climbs or highway passing. It also enhances exhaust tone across the powerband. MagnaFlow retains the factory catalytic converter, so no modifications are needed to the cat pipe or headers. Built from high-quality mandrel-bent stainless steel, it fits snugly and is tough enough for serious off-road use. As one of MagnaFlow’s most affordable exhaust upgrades, it’s a smart first step toward future exhaust mods for your Jeep JK.
