The RIAI Ciing EH28903-2-2D Tube Headers are a high-performance upgrade for your 99-06 Chevy Silverado or GMC Sierra 4.8L, 5.3L, or 6.0L engine. These tube headers are designed to replace the factory exhaust manifolds, improving both power and efficiency.

Each header is constructed from high-quality stainless steel, ensuring durability and resistance to corrosion. The 2-2-2 design features two inlets on each side and two outlets at the rear, allowing for a more efficient exhaust flow and improved scavenging effect.

The EH28903-2-2D headers come with 1.75-inch primaries, which taper down to 1.65-inch collectors. This size reduction at the collector helps to decrease backpressure and increase exhaust velocity, resulting in more power and torque.

These headers are also designed to work seamlessly with factory catalytic converters and oxygen sensors, making them a great choice for those looking for a bolt-on solution. The included gaskets ensure a secure seal, and the headers come with detailed instructions to make the installation process as smooth as possible.

By upgrading to the RIAI Ciing EH28903-2-2D Tube Headers, you can expect improved engine performance, quicker throttle response, and a more pleasing exhaust note. These headers are an excellent choice for those looking to unleash the full potential of their 4.8L, 5.3L, or 6.0L engine in their Chevy Silverado or GMC Sierra.
