The BBK 99-04 GM Truck SUV 4.8 5.3 Shorty Tuned Length Exhaust Headers are high-performance direct fit replacements designed to enhance exhaust flow and engine output. Constructed from 1-5/8 inch CNC mandrel bent tubing, these headers provide unrestricted exhaust flow, increasing horsepower and torque beyond factory OEM manifolds. The tuned length design improves scavenging waves for more efficient combustion, resulting in better performance and fuel economy compared to stock or equal length headers. Featuring a 3/8 inch laser cut flange for added strength and a guaranteed leak-free fit, these headers are robotically and precision hand welded, then pressure tested to ensure durability and long-term reliability. They come finished in a polished silver ceramic coating for corrosion resistance and include all necessary hardware for installation.

These headers are engineered specifically for 1999 to 2004 GM trucks and SUVs equipped with 4.8L and 5.3L engines, providing a direct bolt-on replacement for factory exhaust manifolds. Installation requires transferring the factory OE doughnut gasket from the passenger side manifold to the BBK header to ensure proper mid-pipe fitment and sealing. The kit includes new exhaust header gaskets, bolts, and hardware to complete the upgrade. Ideal for street and light performance applications, these headers improve power delivery and efficiency while maintaining a straightforward installation process for daily drivers and enthusiasts alike.

BBK Performance Exhaust Headers

Fits 1999–2004 GM Trucks and SUVs with 4.8L and 5.3L Engines

Part #: 40050

Overview

These BBK Performance shorty tuned length exhaust headers are engineered as direct-fit replacements for GM trucks and SUVs from 1999 to 2004 equipped with 4.8L and 5.3L engines. Designed for enthusiasts seeking enhanced exhaust flow and improved engine efficiency, these headers help support increased horsepower and torque compared to factory OEM manifolds. Their tuned length design promotes better scavenging waves, which can contribute to improved combustion and fuel economy over stock or equal length headers.

Key Features

BBK exhaust headers combine durable construction with performance-focused design, featuring:

  • 1-5/8 inch CNC mandrel bent tubing for smooth, unrestricted exhaust flow
  • Shorty tuned length design optimized for improved scavenging and combustion
  • 3/8 inch laser cut flange for enhanced strength and a guaranteed leak-free fit
  • Robotically and precision hand welded for long-lasting reliability
  • Pressure tested to ensure durability and performance in real-world conditions
  • Available in polished silver ceramic coated finish for corrosion resistance and attractive appearance
  • Includes new exhaust header gaskets, bolts, and hardware for complete installation

Construction & Design

Manufactured with precision CNC mandrel bending, these headers maintain consistent tubing diameter throughout bends to minimize flow restrictions. The robust laser cut flange adds structural integrity, while the ceramic coating provides heat resistance and corrosion protection, extending the life of the headers under demanding conditions.

Installation & Fitment

Designed as a direct bolt-on replacement for 1999–2004 GM trucks and SUVs with 4.8L and 5.3L engines, installation is straightforward. Note that on the passenger side, the factory OE doughnut gasket must be removed from the original manifold and reinstalled on the BBK header to ensure proper mid-pipe alignment and sealing.
