Unlock the full performance potential of your BMW B46-powered vehicle with the genuine Armytrix Stainless Steel Ceramic Coated Decatted Downpipe, engineered to maximize exhaust flow, reduce back pressure, and improve turbocharger efficiency while providing outstanding thermal protection.
Manufactured from premium T304 stainless steel and finished with a high-temperature ceramic coating, this high-flow decatted downpipe significantly improves exhaust gas flow while reducing radiant heat inside the engine bay. The ceramic coating also enhances corrosion resistance and long-term durability under extreme operating conditions.
Replacing the restrictive factory catalytic converter, the Armytrix downpipe delivers faster turbo spool, sharper throttle response, improved engine responsiveness, and increased horsepower potential while producing a deeper and more aggressive exhaust note.
Designed with an integrated high-flow catalytic simulator, the system ensures precise OEM-quality fitment and installs directly using the original mounting points for a straightforward bolt-on upgrade.
Compatible with a wide range of BMW models equipped with the B46 engine, including selected:
- BMW X3 G01
- BMW 3 Series F30 / F31 / F34
- BMW 3 Series G20 / G21
- BMW 4 Series G22 / G23 / G26
- BMW 5 Series G30 / G31
