BBK 99-04 GM Truck SUV 4.8 5.3 Shorty Tuned Length Exhaust Headers - 1-3/4 Silver Ceramic

When you're looking to get more out of your 1999-2013 GM truck or SUV with a 4.8L or 5.3L engine, these BBK Performance shorty tuned length exhaust headers are a solid choice. They're built to replace your factory manifolds, offering a direct fit that makes installation much simpler. The main job of these headers is to help your engine breathe easier by improving exhaust flow, which can lead to noticeable gains in horsepower and torque compared to stock.

What sets these BBK headers apart is their tuned length design. Unlike equal length headers, the tuned length design helps create improved scavenging waves. This means the exhaust gases are pulled out of the cylinders more efficiently, leading to better combustion. This improved efficiency can translate to better performance and even a slight improvement in fuel economy. They're constructed from 1-3/4 inch CNC mandrel-bent tubing, ensuring smooth bends and no restrictions. The flanges are a beefy 3/8 inch thick and laser cut for a strong, leak-free seal, and the whole assembly is robotically and precision hand-welded for long-term reliability. Plus, they come in a polished silver ceramic coating that looks sharp and helps manage heat.

This kit comes with everything you need to get them installed, including new exhaust header gaskets, header bolts, and all the necessary hardware. A key detail to remember is that on the passenger side, you'll need to remove the factory doughnut gasket from your old manifold and reuse it with the new BBK header to ensure a proper seal with your mid-pipe. This is a popular upgrade for these trucks and SUVs, and with the included hardware and direct-fit design, it's a job you can tackle in your garage.
