Fabspeed Sport Catalysts for Ferrari 328 (1986–1989)

Fabspeed's Ferrari 328 catalyst assemblies replace the original converters with HJS 200-cell cores. Stainless construction and the original-style connection arrangement make this a catalyst-section conversion rather than a rear muffler change. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for Porsche and other sports cars through dynamometer, road and racetrack evaluation.

Emissions Information

These assemblies replace the original catalytic converters. Confirm the certification and permitted application for the exact vehicle before purchase; a catalyst core or catalyst-related fault-code claim alone does not establish road-use approval.
