Transform the exhaust flow on your Audi RS3 8V.2 EA855 Facelift and Audi TTRS 8S EA855 Facelift with the Redstar performance exhaust downpipe. Designed specifically for these models, this 3.5 inch single-tube downpipe replaces the restrictive factory section and removes both the primary and secondary catalytic converters for a clear, direct path out of the turbine.
Engineered for maximum throughput, the optimised single-tube layout reduces backpressure to deliver faster turbo spool, crisper throttle response, and significant power gains. Optional OEM-style heat shielding cuts radiant heat by up to 80% to help manage engine bay temperatures and support consistent performance during demanding use.
Every Redstar downpipe is built from high-grade 2.0mm wall 304 stainless steel, TIG welded and back purged for structural integrity and clean internal welds. An OEM-spec V-band flange and factory-style brackets ensure a true bolt-on fit that integrates with the original mounting points. Precision construction and motorsport-inspired thermal management make this Redstar upgrade the smart choice for enthusiasts seeking flow, response, and durability.
Available Options
- 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.
