Description for Doug Thorley Headers part# 214Y-FI5
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. The Tri-Y configuration builds the most power in the middle rpm range which is great for towing and 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. To prevent leaks these headers have an O-ring welded into the flange in addition to the high-temperature gasket provided.
