Description

If you’re running an LS-series engine in your GMT400 truck or SUV, factory exhaust manifolds are costing you real horsepower and efficiency. This street header features 1-5/8″ primary tubes designed to improve exhaust scavenging and reduce backpressure while maintaining stock collector compatibility—meaning bolt-on installation without fabrication headaches. Built from quality steel with durable black paint, it’s a straightforward bolt-on upgrade that delivers measurable gains in flow and responsiveness.
