## Description

Doug Thorley Headers THY-351-C 4:1 Long Tube Headers deliver the ultimate in performance and for that monster big block motor in your 1968-78 Chevelle or El Camino. With big 2" primary tubes, these 4:1 long tube headers are designed to replace the OE type exhaust manifolds with a performance component that result in a serious increase in exhaust flow over stock!

They are then silver ceramic coated inside and out, which looks great, drastically reduces under-hood temperatures and creates a strong barrier to protect the headers from the environment. This complete kit includes everything needed to seriously upgrade the power output on your vehicle: headers, gaskets, exhaust adapters, and installation hardware.
