Description
If you’re running a 4.8L, 5.3L, or 6.0L LS engine in your full-size GM truck or SUV, factory exhaust restrictions are costing you horsepower and throttle response. This 1-5/8″ primary header flows significantly better than stock, improving scavenging and reducing backpressure to unlock gains across your entire power band. Bolt-on installation means you can have measurable improvements in performance without fabrication work.
