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. Unbeatable Design and Construction Unitronic opted for OEM-style thermal isolation / heat shield to not only protect the engine bay from radiant heat, but also ensure catalyst temperature is reached and maintained for optimal efficiency and function. The large 6" catalytic converters provide exceptional flow and greatly enhances the thunderous sound of the turbocharged 4.0TFSI engine. The smooth post-cat stainless steel transitions continue 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. Maximum Performance with Unitronic Software In order 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 own home or garage. Install The Unitronic Performance Downpipes for the C8 RS 6 and RS 7 are direct OEM replacements.
