Exhaust Headers

These BBK Performance shorty tuned Length exhaust Headers are designed and constructed as direct fit replacements for all 99-04 GM Truck and SUV 4.8L and 5.3L applications. Each header is manufactured with 1-5/8" CNC mandrel bent tubing that offers unrestricted exhaust flow for increased horsepower and torque over factory OEM manifolds. BBK tuned Length headers offer improved scavenging waves for better combustion, which leads to improved performance and fuel economy over stock or equal Length headers. As with all BBK Performance exhaust headers they feature a 3/8" laser cut flange for additional strength and a guaranteed leak free fit. All headers are robotically and precision hand welded and then pressure tested to ensure years of reliability and performance in the real world. All BBK exhaust headers are available in a Titanium Ceramic or polished silver ceramic coated finish and include new exhaust header gaskets, header bolts and hardware to complete the installation. IMPORTANT NOTE: On The passenger side OE Manifold you must remove the factory OE doughnut gasket and reinstall on the BBK passenger side header so the mid pipe will bolt up and seal

BBK CNC Series performance headers are built tough enough to handle the stresses of day-to-day driving or off-roading. These exhaust performance upgrades feature CNC mandrel-bent heavy-gauge tubing and laser-cut flanges that ensure long life and they include gaskets and installation hardware. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment.
