| Stillen 370Z / G37 Hi-Flow Catalytic Converters|
|Stillen now has high flow replacement catalytic converters for the Nissan 370Z and Infiniti G37 Coupe. These are for the enthusiast that wants the best flow possible, while remaining environmentally responsible.
Though these converters are not CARB legal, they are a step above race or test pipes and will result in a less "raspy" tone. As high performance cats, some sound increase should be expected. Stillen Hi Flow Catalytic Converters reduce emissions and unpleasant exhaust smells.
