Long Exhaust Header for Chevrolet Silverado/GMC Sierra (2014-2018) 4.8L/6.2L V8 Engine

Your 6.2L V8 is essentially a Corvette engine trapped in a truck body—it's time to remove the restrictive factory shackles and let it run free with the airflow it demands.

Performance Long Tube Headers & Y-Pipe for Chevy, GMC & Cadillac (4.8L / 6.2L V8)

If you are driving a 2014-2018 GM truck or SUV equipped with the powerhouse 6.2L V8 (L86) or the fleet-spec 4.8L, you are sitting on massive potential. However, the factory exhaust system is designed for silence and emissions compliance, not performance. The stock cast iron manifolds are narrow and convoluted, trapping heat and creating significant backpressure. This Long Tube Header kit is the sledgehammer solution to that restriction.

This system features a massive 2.0-inch primary tube diameter. In the world of LS/LT performance, that is serious volume. These large-diameter runners are designed to support high horsepower builds, supercharged applications, or simply to maximize the top-end pull of the 6.2L engine. By pairing these headers with the included Y-pipe, you create a high-velocity exhaust path that scavenges cylinders efficiently. This 8-2-1 design (8 cylinders to 2 collectors to 1 merge) ensures that exhaust pulses exit smoothly, resulting in a dramatic increase in torque and a thunderous exhaust note.

Constructed from CNC-machined T-304 stainless steel, this kit is built to survive the harsh environment of the undercarriage. The computerized TIG welds ensure structural integrity at the flanges, preventing the warping and leaks common with lesser quality headers. Critical Fitment Note: This kit is engineered specifically for the 4.8L and 6.2L deck heights and exhaust ports. It will NOT fit the 5.3L engine options. Please verify your engine displacement before ordering.

Why You Need This Upgrade

• Massive Airflow Potential: Huge 2.0" (50.8mm) primary tubes are sized for maximum peak horsepower and aggressive builds.
• Complete Exhaust Overhaul: Includes a matching Y-pipe to connect the long tube headers to your existing exhaust system seamlessly.
• Superior Durability: Made from T-304 Stainless Steel to resist corrosion and withstand high exhaust gas temperatures (EGTs).
• Precision Engineering: CNC machined flanges and computerized TIG welding ensure a flat seal against the head to prevent exhaust ticks.
• Direct Bolt-On: Utilizes pre-welded hangers for factory fitment points (though professional installation is recommended).

Installation Notes

Long tube headers are a significant modification. Due to tight clearances in the engine bay of 2WD and 4WD K2XX platform trucks, professional installation is highly recommended. This kit does not include installation guides. Important: Because this system alters the position of the catalytic converters (or removes them depending on your setup), a custom ECU tune is strongly advised to prevent Check Engine Lights and to optimize fuel trim for the increased airflow.
