Upgrade your truck's exhaust flow and throttle response with BBK Performance shorty tuned length headers. Engineered as a direct-fit replacement for restrictive factory cast iron manifolds, these headers utilize 1-3/4 inch CNC mandrel-bent tubing to ensure unrestricted exhaust flow. The tuned length design optimizes scavenging waves, improving combustion efficiency to deliver measurable gains in horsepower, torque, and fuel economy.

Built for the rigors of truck applications, these headers feature heavy-duty 3/8-inch laser-cut flanges that provide additional strength and a guaranteed leak-free seal against the cylinder head. Every unit is robotically and precision hand-welded, followed by a thorough pressure test to ensure long-term reliability. The titanium ceramic finish offers superior thermal insulation, significantly reducing under-hood temperatures while protecting the headers from corrosion and blueing.
