MBRP 2.5" Armor Plus Off-Road Cat-Back Exhaust (S5514409) - 2007–2011 Jeep Wrangler JK 3.8L
The MBRP Armor Plus 2.5-inch Off-Road Cat-Back Exhaust is engineered for 2007–2011 Jeep Wrangler JK owners who demand maximum durability, aggressive sound, and trail-ready clearance. Featuring a high-clearance turndown exit and muffler-before-axle layout, this system is ideal for off-road builds where ground clearance and underbody protection are critical.
Constructed from rugged T409 stainless steel, the Armor Plus series delivers excellent resistance to corrosion, impacts, and harsh environmental conditions. This material provides a budget-friendly entry into stainless steel exhaust systems while still offering long-term reliability. MBRP backs this system with an industry-leading lifetime warranty.
The race-profile muffler produces a bold, aggressive exhaust tone that brings the 3.8L V6 to life without restricting exhaust flow. Smooth mandrel-bent 2.5-inch tubing improves efficiency and throttle response, while welded-on hangers ensure secure, long-lasting fitment whether on the road or the trail.
Designed with a turndown exit and no exposed exhaust tip, this system stays tucked high and out of harm’s way when navigating rocks, ruts, and uneven terrain. Installation is straightforward thanks to a direct bolt-on design that utilizes factory mounting locations.
