The Thermal R&D B907-C907 is a 3" catback exhaust for the 2014 through 2019 Ford Fiesta ST. Built in Lancaster, California from T304 stainless steel, the B907-C907 transforms the Fiesta ST's exhaust note from the muted factory tone to a crisp, engaging sport sound that matches the car's spirited character. Thermal R&D's patented Helmholtz resonator technology is tuned to the Fiesta ST's 1.6L EcoBoost four-cylinder to eliminate drone at highway speeds, making it equally suited to daily commuting and weekend canyon runs. Dual polished stainless tips exit cleanly beneath the Fiesta ST's rear bumper. Installation is a direct bolt-on requiring no modifications.
