New B9 A4 and A5 2.0T ECS High Flow Cat
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.
