Description

Unitronic is happy to release their Performance Downpipes for the 2020+ C8 RS 6 and RS 7 equipped with the 4.0TFSI EA825 (DJPB) engine. 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, from our 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.

The large 6" catalytic converters provide exceptional flow and greatly enhance the thunderous sound of the turbocharged 4.0TFSI engine. The smooth post-cat stainless steel transitions lead into dual 4.5" T304 stainless steel tubing, terminating at the factory 3-bolt mid-pipe flanges to ensure a seamless direct bolt-on fitment.

One key development area for Unitronic Engineers was the catalytic converter on these Performance Downpipes. While working closely with GESi through several iterations of their G-Sport Emissions Systems Catalytic Converters over the years, our goal once again was to ensure this product would satisfy our compliance demands while fulfilling Unitronic's performance-related goals. The team quickly opted for dual GESi 6" UHOX converters for these Performance Downpipes, which met the requirements for the C8 4.0TFSI while being rated for a massive 1200HP.

To take full advantage of these all-new Performance Downpipes, Unitronic Stage 2 ECU Software is now available for the C8 RS 6 and RS 7. With testing and validations completed, power outputs are increased by up to +219HP / +166LB-FT with Unitronic Stage 2 93octane/98ron Performance Software for a maximum of 819HP / 760LB-FT. This software upgrade is entirely compatible with our UniCONNECT+ cable, empowering Clients to tune their vehicles directly through the OBD-2 port within minutes from the comfort of their homes or garage.
