The Supreme SP for the Ford Focus ST combines, classic GReddy styling and sound to boost power from the modern American EcoBoost powerplant. Large 76mm (3”) diameter mandrel piping is carefully routed beneath ST chassis through two inline, compact Supreme SP straight-through muffler sections. Dual 102mm (4”) GReddy double walled tips perfectly finish-off the system through the center exit bumper. Power tests have shown substantial increase in mid-range power and torque, with peak gains of 24whp and 11ft.lbs.
Note: kit includes spacers to remount the under brace lower, to make clearance for the larger diameter piping.
