Product Description

The BBK 4005 Shorty Exhaust Headers are engineered to improve exhaust efficiency on GM full-size trucks and SUVs equipped with the 4.8L or 5.3L V8 engine. By replacing restrictive factory exhaust manifolds, these headers allow exhaust gases to exit the engine more efficiently, resulting in improved throttle response, increased horsepower, and enhanced torque across the RPM range.

Constructed from durable mild steel and finished with a high-temperature ceramic coating, the BBK 4005 headers are designed for long-term performance and heat management. Their shorty-style configuration maintains factory catalytic converter placement and ensures emissions compliance while delivering a noticeable performance upgrade. Designed as a true bolt-on solution, these headers are ideal for daily drivers, towing vehicles, and performance-minded truck owners seeking reliable gains without complex installation.
