Unlock the full performance potential of your BMW OPF-equipped vehicle with the genuine Armytrix Stainless Steel Decatted Downpipe, engineered to maximize exhaust flow, reduce back pressure, and deliver sharper throttle response and enhanced turbocharger efficiency.
Manufactured from premium T304 stainless steel, this high-flow decatted downpipe replaces the restrictive factory catalytic converter while offering exceptional durability, heat resistance, and corrosion protection. Its optimized internal flow design minimizes exhaust restrictions, allowing the turbocharger to spool faster while improving engine responsiveness and overall driving dynamics.
Specifically developed for modern BMW models equipped with OPF (Otto Particulate Filter), this downpipe also produces a noticeably deeper and more aggressive exhaust tone, creating a more engaging driving experience without compromising OEM-quality fitment.
Designed as a direct bolt-on upgrade, the Armytrix downpipe installs using the factory mounting points for precise fitment and straightforward installation.

- BMW X5 G05 50e (490 hp)
- BMW Z4 G29 M40i (340 hp)
