BBK Performance 1-3/4 in. Tuned Length Shorty Exhaust Headers - Titanium Ceramic - Select 1999-2013 GM Truck/SUV (6.0L / V8-6.0L)

Fits select 1999-2013 Cadillac, Chevrolet, and GMC full-size trucks and SUVs (6.0L / V8-6.0L).

BBK Performance tuned length shorty exhaust headers are engineered to replace restrictive factory cast iron manifolds, providing a direct-fit upgrade that improves exhaust scavenging and engine efficiency. These headers feature 1-3/4 inch CNC mandrel-bent tubing to ensure unrestricted flow, leading to increased horsepower and torque across the RPM range. The heavy-duty 3/8 inch laser-cut header flanges provide a flat, stable sealing surface for a guaranteed leak-free fit.

Each header is precision robotically and hand-welded before undergoing pressure testing to ensure long-term reliability in demanding environments. The titanium ceramic finish provides a durable barrier against corrosion while significantly reducing under-hood temperatures. This kit comes complete with new gaskets and high-quality hardware for a straightforward bolt-on installation.
