This item has been discontinued by the manufacturer and is no longer available. For alternative products please contact us.

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. Common gains for these HFCs are 9 HP on the 350Z and 16 HP on the 370Z.
