MBRP 3IN HIGH CLEAR BYPASS 2020-23 WRANGLER JL ECODIESEL

On a trail-built Wrangler, the factory exhaust can become one more low-hanging component waiting to introduce itself to a rock. The MBRP S6501409 High Clearance 3-Inch Muffler Bypass Kit for the 2020–2023 Jeep Wrangler JL with the 3.0L EcoDiesel replaces the factory rear exhaust section with a much more compact turndown configuration. By eliminating the large rear muffler and tailpipe arrangement, MBRP moves the exhaust exit up and out of harm's way, creating additional clearance where it matters when dropping off ledges, climbing over obstacles, or working through deeply rutted terrain.

The system is constructed from 3-inch T409 stainless steel as part of MBRP's Armor Plus Series. This material delivers the durability and corrosion resistance needed for an exhaust system exposed to water, mud, road salt, heat cycles, and off-road abuse. Heavy-duty construction and welded hangers further reinforce the system for demanding use, making the S6501409 particularly well suited for an EcoDiesel Wrangler that regularly ventures beyond pavement.

Despite eliminating the rear muffler, this isn't designed to turn the EcoDiesel into a highway drone machine. MBRP classifies the S6501409 with its Tour Profile and specifies no sound increase over the stock exhaust for this application. That makes the upgrade particularly appealing for daily-driven Wranglers where the goal is additional trail clearance and a more streamlined exhaust layout without sacrificing cabin comfort during long highway drives.

The S6501409 is a filter-back system, meaning it replaces the exhaust downstream of the factory diesel particulate filter while retaining the vehicle's emissions equipment. The freer, simplified routing uses a rear turndown exit instead of extending a conventional tailpipe toward the back bumper. Beyond improving clearance, the tucked configuration eliminates an exhaust tip hanging near the rear of the Jeep where it could potentially be damaged during steep departures or contact with trail obstacles.

Installation is designed around the factory Wrangler rather than requiring fabrication. The system uses the Jeep's original hanger locations and includes the clamps and components needed for a bolt-on installation. No welding is required, and MBRP estimates installation at roughly 1.5 to 2 hours. For EcoDiesel owners who prioritize ground clearance, corrosion-resistant construction, and simple trail functionality over a flashy exhaust tip or aggressive exhaust note, the MBRP S6501409 is a refreshingly purpose-built upgrade.

Technical Specifications: 3-inch filter-back exhaust system constructed from T409 stainless steel with a high-clearance turndown exit. MBRP Armor Plus Series with a Tour sound profile, no significant sound increase over stock, welded hangers, bolt-on installation, and a lifetime manufacturer's warranty.

Fitment Note: Designed for 2020–2023 Jeep Wrangler JL models equipped with the 3.0L EcoDiesel engine. This system installs downstream of the factory diesel particulate filter and is designed to retain the vehicle's factory emissions equipment.
