The BBK 4021 long tube exhaust header system delivers maximum performance gains for LS3 and L99 powered Camaros. This complete system features 1-3/4" diameter primary tubes with a stunning chrome finish and includes high-flow catalytic converters for 50-state legal emissions compliance.

Key Features:

Full-length long tube design maximizes exhaust scavenging and horsepower gains
1-3/4" mandrel-bent primary tubes optimize flow for LS3 and L99 engines
High-quality chrome finish provides show-quality appearance and corrosion resistance
Includes high-flow catalytic converters for emissions compliance
Precision CNC-machined flanges ensure leak-free installation
Engineered specifically for 2010-2015 Camaro LS3 and L99 V8 applications

BBK Performance long tube headers are engineered to deliver significant power and torque increases throughout the RPM range while maintaining a deep, aggressive exhaust note. The included catalytic converters allow this system to pass emissions testing while still providing substantial performance improvements over restrictive factory manifolds.
