The EVOlution GT for the Ford Fiesta ST provides great sound with a good boost in performance and looks. The large 76mm (3”) mandrel bent piping help expel exhaust gases from the Fiesta’s 1.6L Ecoboost engine to the tune of 9hp and 8ft-lbs of torque, on a completely stock ST. Sound is controlled to a deep sophisticated growl with the use of our straight-though EVO muffler and large resonator. The unique design of our compact EVO muffler with off-set 105mm (4.1”) tip allow for a stylish fitment; fitting for the sporty ST model. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
