Unleash the potential of your 2016+ Alfa-Romeo Giulia Tipo 952 QV 2.9L F154 twin-turbocharged V6 and 2020+ Alfa Romeo Giulia GTA with Redstar performance exhaust downpipes. Engineered as a direct, bolt-on replacement for the OEM downpipe section, this system is purpose-built to free the exhaust path on the F154 V6 for maximum flow and response.

Experience crisper throttle modulation, faster turbo spool, and tangible gains in power delivery, alongside a deeper, more engaging exhaust tone. Optional OEM-style heat shielding reduces radiant exhaust heat by up to 80% to help protect surrounding components and stabilise under-bonnet temperatures. Configure your system with ultra high-performance HJS 200cpsi or GESI GEN2 400cpsi catalytic converters, or choose Competition/Catless for ultimate flow.

Crafted for durability and precision fit, every Redstar downpipe uses 2.0mm wall 304L stainless steel, is 100% TIG welded and back purged, and integrates OEM-spec V-band flanges with factory-style brackets. This is Redstar engineering focused on performance, reliability, and a refined Redstar sound for the Giulia QV and Giulia GTA.

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.
