Stainless Steel Manifold Headers for Nissan Titan / Armada & Infiniti QX56 5.6L V8 (2004–2015)
Unlock more power and performance from your full-size truck or SUV with these stainless steel manifold headers engineered specifically for the 5.6L V8 engine. Designed to replace the restrictive factory exhaust manifolds, these headers allow exhaust gases to exit more efficiently, delivering noticeable gains in horsepower and torque, improved throttle response, and a more aggressive exhaust note.
The Titan, Armada, and QX56 are known for their robust V8 power and towing capability. These headers enhance that performance by reducing exhaust backpressure and improving exhaust flow throughout the RPM range. The result is an estimated 10–15 horsepower and torque increase, smoother power delivery, and better engine breathing—whether you're towing heavy loads, accelerating onto the highway, or tackling demanding terrain.
In addition to performance improvements, these headers transform the driving experience with a deeper, more aggressive exhaust tone that brings out the true character of the 5.6L V8. The 6-2 piping design optimizes exhaust scavenging for improved efficiency, while the durable stainless steel construction ensures long-lasting performance and corrosion resistance even in harsh conditions.
