Transform your Audi C8 A6 and A7 with Redstar Exhaust's Performance Downpipe engineered for the 55 TFSI 3.0 Turbo. Precisely tailored for 2018+ Audi A7 C8/C8.5 Sportback Sedan and 2019+ Audi A6 C8/C8.5 Sedan/Allroad applications, this performance exhaust upgrade targets the turbocharged 3.0T powertrain for a seamless, model-specific fit.

Expect a tangible step up in response and drivability. The Redstar downpipe is developed to deliver significant power gains with faster spool and crisper throttle response, while helping to reduce under-bonnet temperatures. Optional OEM-style heat shielding cuts radiant heat by up to 80% for improved thermal control. Choose from high-performance catalytic converter options or a competition catless configuration to suit your goals.

Built for longevity and consistent performance, each unit uses 2.0mm wall 304 stainless steel, is 100% TIG welded and back purged, and integrates with OEM-spec V-band flanges and factory-style brackets for a true bolt-on installation. Backed by RedstarÕs motorsport-informed approach and premium manufacturing standards, this downpipe for the Audi A6 and A7 C8 platforms elevates flow, sound, and response while retaining OEM-like fitment.
