DougThorley 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.
