Unleash performance from your Audi 3.0 TFSI V6 Supercharged platform with Redstar Test Pipes, engineered for the 2010-2016 Audi S4 B8 B8.5, 2009-2017 Audi S5 B8 B8.5, 2012-2018 Audi SQ5 B8, 2013-2018 Audi A6 C7 C7.5, 2012-2018 Audi A7 C7 C7.5, and 2012-2018 Audi A8 D4. These high-flow test pipes replace the restrictive factory catalytic converters to free up exhaust flow and unlock the efficiency potential of the supercharged 3.0 TFSI.
With 2.5in tubing and carefully engineered, flow-optimised transitions to OEM-spec bottom flanges, the Redstar design reduces backpressure and enhances engine breathing. Expect crisper throttle response, measurable power gains, and a richer exhaust character. For superior thermal control, the optional OEM-style Heat Shielding uses a ceramic inner liner and embossed outer foil to cut radiant exhaust heat by up to 80%.
Built for long-term reliability, each assembly is crafted from 2.0mm wall 304L stainless steel, 100% TIG welded and back purged, and finished with double walled ends and precision CNC machined flanges. OEM-style brackets and mounts ensure a true bolt-on fit for both LHD and RHD applications. Backed by a lifetime warranty, this is a Redstar performance exhaust upgrade you can rely on.
