Product Description

The JBA 40-1405 Cat Back Exhaust System is a direct-fit performance exhaust upgrade for 2004-2014 Nissan Armada SUVs equipped with the 5.6L V8 engine. Built with mandrel-bent 3.00" stainless steel tubing and featuring a high-flow muffler, this cat-back system enhances exhaust flow, increases horsepower and torque, and delivers a richer, more aggressive exhaust tone compared to the stock system. It retains factory-style mounting points for a bolt-on installation and includes all necessary hardware and a chrome-finished exhaust tip for increased visual appeal.

Designed for enthusiasts who want both improved performance and a deeper exhaust note without major modifications, the 40-1405 maintains everyday drivability while providing noticeable gains in throttle response and exhaust flow. Passenger-side single exit styling adds a sporty look, and the quality stainless steel materials resist corrosion and discoloring for long life.
