Unleash the performance potential of your Audi C8 S6 Sedan/Avant and C8 S7 Sportback 2.9L Twin Turbo V6 with the Redstar Exhaust Downpipes and Front Resonator delete system. This upgrade replaces the restrictive factory downpipes and removes the front resonator section to open up the exhaust path for your 2.9L biturbo powertrain.
Engineered with a flow-optimised smooth transition design to cut backpressure, the Redstar system promotes faster turbo spool and sharper throttle response. When paired with ECU calibration, it is built to support substantial power increases and suits high-output builds including big-turbo upgrades. Optional motorsport-inspired thermal shielding reduces radiant heat by up to 80% to help keep under-bonnet temperatures in check.
Manufactured from premium 2.0mm wall 304L stainless steel with 100% TIG-welded, back-purged joints and OEM-spec V-band interfaces, this Redstar performance exhaust solution delivers robust durability with true bolt-on fitment. LHD and RHD compatibility ensures precise installation across global platforms while preserving the unmistakable Redstar sound and quality.
Available Options
- HJS HD 200cpsi Catalytic Converters: Engineered in Germany and trusted worldwide, the HJS 200cpsi ultra high-performance cats are rated for over 1000hp. Renowned for exceptional flow, durability, and consistent quality, these converters set the benchmark for high-output applications. Ideal for drivers demanding maximum performance without compromise.
- GESI GEN2 400cpsi Catalytic Converters: The latest GEN2 series from GESI is rated to support up to 1000hp while offering smoother exhaust flow and improved efficiency compared with factory units. Featuring advanced emissions technology for optimal catalyst function at high flow rates. A strong choice for those seeking significant performance gains with refined operation.
- OEM-Style Heat Shielding: Redstar's signature thermal management system reduces radiant exhaust heat by up to 80%. Developed with motorsport-inspired materials and construction, it uses a multi-layer design of ceramic insulation and embossed stainless steel foil. Unlike wraps or coatings that degrade quickly, Redstar shielding delivers long-term durability and consistent protection for engine bay components.
- Competition/Catless: Maximum flow design for uncompromised performance. Delivers the most aggressive exhaust note and optimal power gains. Track use only - not for road use.
- OPF: For European emission controlled vehicles only.
- Straight Tunable O2 Spacers: Includes 3 inserts to restrict flow to the O2 sensor to help set readiness and minimise check engine light risk when using the Competition model without appropriate tuning.
- V-band Downpipe to Front Resonator Delete Connection: Secure V-band interface between the downpipes and the front resonator delete section.
