Doug Thorley Headers

Backed by 40-plus years of knowledge and experience, Thorley headers are designed to outflow your stock exhaust manifolds. These headers increase gas mileage and give your engine more horsepower across the entire rpm range. Their design configuration builds the most power across the rpm range, which is great for everything from street/strip performance, to towing, to steep grades. To make these headers last, Thorley made them out of durable 14-gauge mild steel with 3/8 in. thick flanges and 5/16 in. collector rings or 13 gauge stainless steel with ½ in. thick flanges and topped them off with a good looking, nickel chrome plated finish or a high temperature ceramic coating. To prevent leaks, these headers have an O-ring welded into the flange, in addition to the high-temperature gasket provided. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment.
