Sport Catalytic Converters
Sport catalytic converters for the Ferrari 328 (1986-1989), replacing the heavy, restrictive factory cats with Fabspeed's 200-cell HJS high-flow units. On the dyno they added 10whp and 7 lb-ft of torque, with a moderate volume increase and a higher-pitched motorsport tone, without any interior drone. Built from CNC mandrel-bent T304L stainless steel with no catalyst-related check engine light guaranteed. Bolt-on installation, no cutting or welding required.

Does it add interior drone?

Is it covered by warranty?
