Stainless Steel Headers for Nissan Titan/Armada & Infiniti QX56 5.6L V8
The Nissan VK56DE V8 powers three of the most capable full-size vehicles ever built—the Titan truck, Armada SUV, and luxurious Infiniti QX56. This proven 5.6L powerplant delivers 317-400 horsepower depending on year and application, but restrictive factory exhaust manifolds leave significant performance on the table. Our precision-engineered stainless steel headers unlock 10-15 horsepower and torque gains throughout the powerband, transforming towing capability, acceleration, and throttle response while adding the aggressive V8 soundtrack these impressive machines deserve.
Unleash Full-Size V8 Performance
Experience dramatic improvements as optimized 6-2-1 header design with 1-7/8" x 1-3/8" stepped primaries feeding 3" collectors eliminates exhaust restriction. Factory cast manifolds create backpressure that limits power precisely when you need it most—towing heavy trailers, accelerating with passengers and gear, or conquering challenging terrain. These headers optimize exhaust scavenging for measurable gains: stronger low-end torque for confident towing, enhanced mid-range acceleration for passing, improved high-RPM breathing, and the deep, muscular exhaust note that announces serious capability.
Premium Engineering for Heavy-Duty Performance
Constructed from high-grade stainless steel with precision CNC-machined flanges and professional TIG/MIG welded joints, these headers withstand the demanding conditions of towing, hauling, and off-road use. Four O2 sensor bungs maintain proper emissions functionality across all catalytic converters. The robust construction resists cracking from thermal cycling and vibration while the stainless finish provides lasting corrosion resistance. This is the quality heavy-duty truck and SUV owners demand for vehicles that work hard and play harder.
Professional Installation Recommended
These headers require comprehensive exhaust work including removal of factory manifolds and proper integration with downstream exhaust components. Installation instructions are not included—consult factory service manual or experienced shop familiar with VK56DE platforms. The investment in proper installation ensures optimal performance, leak-free operation, and years of enhanced capability from your Nissan or Infiniti V8.
