SSXAU975 - Milltek Sport 80mm Race Exhaust System - Audi RS3 8Y Sportback (OPF/GPF Back)

Unleash the iconic sound of the 5-cylinder with the Milltek Sport exhaust system (Part number: SSXAU975). Specifically developed for the Audi RS3 8Y Sportback, this "Race Non-Resonated" configuration is the most extreme (Loudest) version in the range, offering an unfiltered listening experience and top-tier performance.

Motorsport Engineering: The "Loudest" 80mm System

The Milltek SSXAU975 system is an "OPF/GPF Back" type line, designed to install after the original particulate filter. Unlike conventional systems, this version uses oversized 80 mm (3.15 inches) diameter piping. Made from stainless steel T304L of aerospace grade, it ensures exceptional durability under the demands of motorsport.

In Non-Resonated (no resonator) and Race configuration, this system is engineered to deliver the highest possible sound volume. The drastic reduction in back pressure promotes ultra-fast gas evacuation, improving the responsiveness of the 2.5 TFSI engine and reducing turbo lag.

Technical Features and Highlights:

• Enlarged Diameter: Piping of 80 mm for maximum gas flow (High-Flow).
• Race Configuration: "Loudest" version for an aggressive, pure 5-cylinder sound signature.
• Premium Material: Full construction in T304L stainless steel, the standard in performance tuning.
• Valvetronic System: Integrates exhaust valves controlled by the original Audi Drive Select driving modes.
• Integration: Designed to reuse the original exhaust tips of your RS3 diffuser.
• Flow Optimization: Essential for vehicles used for Track Days or Stage 1 / Stage 2 tunes.
