Enhance the performance of your BMW 5 Series F07, F10, or F11 with the genuine Armytrix Stainless Steel Decatted Downpipe, engineered to improve exhaust flow, reduce turbo back pressure, and unlock 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, enhanced throttle response, increased horsepower 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 and OEM-quality fitment for long-term reliability.

Compatible with selected BMW 5 Series F07 Gran Turismo, F10 Sedan, and F11 Touring Facelift 535i models, this direct bolt-on upgrade is ideal for enthusiasts looking to maximize engine performance while maintaining premium build quality.

At Racebox, we proudly offer only genuine Armytrix performance products, delivering world-class engineering, premium craftsmanship, and motorsport-inspired performance upgrades.
