Unitronic Performance Downpipes for C8 RS6/RS7


These downpipes are a direct bolt-on upgrade, designed to optimally eliminate unwanted restrictions in the factory downpipes, reduce turbo lag and enhance the exhaust note, while utilizing a 6” 400cpsi ultra high output catalytic converter, designed in partnership with Unitronic, by their emissions partners at Global Emissions Systems Inc (GESi).

GESi’s GEN2 ultra-high output UHOX catalytic converters were designed in conjunction with Unitronic for several 2017+ Audi and Volkswagen® applications, rated at up to 1200HP by GESi. Paired with Unitronic Stage 2 Performance Software and other supporting bolt-ons, these Performance Downpipes help yield up to 819HP / 760LB-FT.
