High-flow downpipe from Armytrix dedicated to BMW M5 F10 & M6 F12 / F13.
The component is made of stainless steel. The downpipe removes the factory catalytic converter.
Modifying the front part of the exhaust significantly reduces back pressure. This translates to an increase in the car's power and a much more aggressive sound.
Armytrix downpipes are sold with a system that eliminates errors in the engine control unit.
Optionally, a version coated with ceramic coating can be ordered.
