Upgrade your Audi A5 B9 with the genuine Armytrix Stainless Steel Decatted Downpipe, engineered to maximize exhaust flow, reduce turbo back pressure, and deliver a more responsive, performance-focused driving experience.
Manufactured from premium T304 stainless steel, this high-flow decatted downpipe replaces the restrictive factory catalytic converter, allowing exhaust gases to flow more efficiently. The result is faster turbo spool, sharper throttle response, improved power delivery, and a deeper, more aggressive exhaust note.
Featuring an integrated high-flow catalyst simulator, the Armytrix Downpipe is designed to optimize exhaust efficiency while maintaining compatibility with supported vehicle electronics. Precision TIG welding and corrosion-resistant materials ensure long-lasting durability and OEM-quality fitment.
Compatible with selected Audi A5 B9 2.0 TFSI models, including Coupé and Sportback variants, this direct bolt-on upgrade is ideal for enthusiasts seeking premium aftermarket performance and motorsport-inspired sound.
At Racebox, we proudly offer only genuine Armytrix performance products, delivering world-class engineering, premium craftsmanship, and performance upgrades trusted by enthusiasts worldwide.
