Meets or Exceeds Local Testing Standards
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 a GESi 5" UHOX converter for this Performance Downpipe, which met the requirements for the 2.0TSI EA888 EVO4 engine, while being rated for a massive 1000HP.
Unbeatable Design and Construction
In order to meet the power demands of the new 2.0TSI EA888 EVO4 engine, Unitronic designed and incorporated high quality CFD optimized castings in the upper downpipe section which are heat resistant and provide exceptional flow into the large 5" catalytic converter. Exhaust gasses continue through the OEM-style corrugated mesh flex bellow into the stainless steel midpipe section and reducer, all secured by v-band clamps and centering rings.
Maximum Performance with Unitronic Software
In order to take full advantage of this all-new Performance Downpipe, Unitronic Stage 2 ECU Software is now available for the MK8 Golf R and 8Y S3. With testing and validations completed, power outputs are increased by up to +133HP / +121LB-FT with Unitronic Stage 2 93 octane Performance Software for a maximum of 470HP / 431LB-FT with even more to come. 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.
The Unitronic Performance Downpipe for the MK8 Golf R and 8Y S3 is a direct OEM replacement. Using 3D modeling technology, Unitronic's Downpipe features precise fitment allowing it to be installed within a matter of hours with moderate mechanical knowledge and tools.
