American Racing Headers Ford Mustang S550 headers are designed to handle huge power, even on supercharged applications. Available with or without catalytic converters. Each primary tube is sized to generate the greatest horsepower with the least amount of restriction. Efficient, state-of-the-art merge collectors are tuned for maximum horsepower and torque. Designed to work with aftermarket Catbacks exclusively, a simple mark and cut (no welding required) mates the ARH Bottleneck Eliminator to your Catback. The latest generation of Mustangs brought performance and handling to a whole new level, but power and torque as still waiting to be unleashed from an anemic factory exhaust. Our Bottleneck Eliminator Kit unlocks that power with performance gains up to 30 RWHP and does away with the 2-1/4" restriction at the Catback connection point.
