Unleash up to 14 WHP with an ECS High Flow 200 Cell Catalytic Converter!

ECS B9 2.0T High Flow Catalytic Converter



The perfect way to unleash hidden horsepower in a modern turbocharged engine is to upgrade the restrictive factory catalytic converter with a smoother, higher flowing unit.
Ideal performance is achieved through expelling exhaust gasses at maximum velocity through a larger internal diameter and a less-restrictive catalytic converter.
Through multiple design iterations and stringent product testing, we have engineered our High Flow Catalytic Converter to not only free up horsepower but to provide trouble-free installation.
