Unlock the performance potential of your BMW (07/2013+ models) with the genuine Armytrix Stainless Steel Decatted Downpipe, engineered to maximize exhaust flow, reduce turbo back pressure, and deliver a sharper, more responsive driving experience.
Manufactured from premium T304 stainless steel, this high-flow decatted downpipe replaces the restrictive factory catalytic converter, allowing exhaust gases to exit more efficiently. The result is faster turbo spool, improved throttle response, increased power potential, and a deeper, motorsport-inspired exhaust note.
Equipped with an integrated high-flow catalyst simulator, the downpipe is designed to optimize exhaust efficiency while maintaining compatibility with supported vehicle electronics. Precision TIG welding and corrosion-resistant materials ensure exceptional durability, reliability, and OEM-quality fitment.
Compatible with a wide range of BMW F-Series performance models manufactured from July 2013 onwards, including the M135i, M235i, M235i Cabriolet, M2, M2 Competition, and selected 335i Touring variants, this direct bolt-on upgrade is ideal for enthusiasts seeking premium aftermarket quality and enhanced driving performance.
At Racebox, we proudly offer only genuine Armytrix performance products, delivering world-class engineering, premium craftsmanship, and motorsport-inspired performance upgrades.
