Unlock the performance potential of your BMW 3 Series F30, F31, or F34 Gran Turismo with the genuine Armytrix Stainless Steel Decatted Downpipe, engineered to improve 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 improved turbo spool, faster throttle response, increased horsepower potential, and a deeper, more aggressive exhaust note.
Equipped with an integrated high-flow catalyst simulator, the downpipe is designed to maximize performance while maintaining compatibility with supported vehicle electronics. Precision TIG welding and corrosion-resistant materials ensure exceptional durability and OEM-quality fitment under demanding driving conditions.
Designed for selected BMW 3 Series F30, F31, and F34 Gran Turismo models, including the 320i, this direct bolt-on upgrade is ideal for enthusiasts seeking premium aftermarket quality and motorsport-inspired performance.
At Racebox, we proudly offer only genuine Armytrix performance products, delivering world-class engineering, premium craftsmanship, and exceptional performance upgrades.
