Fabspeed Cat Bypass Pipe for Ferrari 328 (1986–1989)

The Fabspeed Ferrari 328 bypass replaces the catalytic-converter section with straight-through stainless pipework. It removes the catalyst element and increases exhaust volume for a competition configuration. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport engineers sports-car exhaust, intake and ECU tuning products, including Porsche applications, with development on the dyno, road and racetrack.
