MBRP Armor Plus 2.5-Inch Axle-Back Muffler Bypass Exhaust for 2018-2020 Jeep Wrangler JL 3.6L

RELIABILITY BACKED FOR A LIFETIME - ARMOR PLUS Series exhaust systems are crafted from corrosion-resistant T409 Stainless Steel - a value-oriented material designed to protect from penetrating rust and will stand up to almost anything you can throw at it. T409 Stainless Steel tubing is easy to clean. If you’re looking for a performance exhaust system with a Lifetime Warranty, this is probably the one for you. If you don’t find yourself faced with lots of precipitation and salt, this is all you’re ever going to need. All of the tubing is mandrel bent for maximum exhaust flow. Mandrel bending ensures no rippling in the bends. The end result is that it gives you more fresh air inside your engine’s cylinders, allowing it to produce more power and improve vehicle performance and longevity. It's important to note that T409 Stainless Steel is resistant to penetrating rust but winter conditions, heavy salt air, and road treatments might accelerate the corrosion process, these conditions are not covered by MBRP's manufacturer warranty unless the part or system fails completely. When it comes to a performance exhaust system, choose the MBRP ARMOR PLUS Series for a reliable option backed for a lifetime.

Upgrade the exhaust character and flow of your Jeep Wrangler JL with the MBRP Armor Plus Axle-Back Muffler Bypass Exhaust System. Designed for 2018-2020 Jeep Wrangler models equipped with the 3.6L engine, this system provides a high-clearance, single-rear-exit configuration with a 4-inch outlet tip. The MBRP Part Number S5527409 is engineered as a direct bolt-on solution for compatible 2-door and 4-door applications.

Constructed from corrosion-resistant T409 stainless steel, the MBRP Armor Plus system is built to withstand demanding driving conditions while offering easy cleaning and dependable service life. Mandrel-bent tubing helps maintain smooth internal airflow by minimizing restrictions through the bends, supporting improved exhaust flow and engine performance. The high-clearance design helps protect the system during off-road use, while the axle-back muffler bypass configuration delivers a more pronounced exhaust sound without replacing the complete exhaust system.

Installation is designed to be straightforward using the vehicle’s existing mounting locations, with no extensive modifications typically required. This system includes the required exhaust components and does not require a separate exhaust tip. MBRP backs the Armor Plus Series with a lifetime warranty, subject to applicable terms and exclusions. T409 stainless steel resists penetrating rust, but exposure to winter road salt, heavy salt air, and road treatments may accelerate surface corrosion and is not covered unless the part or system fails completely. This product is not CARB approved and may not be legal for use in all emissions-regulated applications. Verify local requirements and vehicle compatibility before installation.
