Redstar Audi C7 S6 S7 RS6 RS7/D4 A8 S8 4.0T Downpipes
Pairs well with
Unleash performance in your Audi S6, RS6, S7, RS7, A8, or S8 with the Redstar Exhaust Performance Downpipes engineered for the 4.0T TFSI platform across C7, C7.5, D4, and D4.5. These downpipes feature an OEM X-crossing design with 3 in tubing transitioning smoothly to OEM-spec bottom flanges, and are designed to fit OEM mid-pipes for a precise interface. No O2 wire extensions are required.
Flow-optimised geometry reduces backpressure to sharpen turbo spool, improve throttle response, and unlock meaningful power gains while adding a richer, more assertive exhaust note. Optional OEM-style heat shielding utilises motorsport-inspired construction to cut radiant exhaust heat by up to 80%, helping stabilise under-bonnet temperatures and support turbo longevity.
Constructed from 2 mm wall T304L stainless steel and built for durability, Redstar downpipes deliver a high-quality solution that installs cleanly and integrates with factory systems. LHD and RHD compliant, they provide a focused upgrade path for Audi S6, RS6, S7, RS7, A8, and S8 owners seeking a premium performance exhaust downpipe solution with Redstar engineering credibility.
