Refined from four decades of racing competition, the Vance & Hines Stainless 2-into-1 Upsweep looks the part and does not disappoint, featuring gorgeous hand TIG-welds on lightweight high-grade stainless steel and a brushed “works” finish. Now integrating our innovative PCX technology with a chambered high-flow catalyst, the Stainless 2-into-1 Upsweep generates stronger low to mid-range torque and an unrivaled roar that can only come from a truly race-inspired 2-into-1 exhaust system.
