Fabspeed Cat Bypass Pipes for Ferrari 348/Mondial T (1989–1995)

These Fabspeed pipes remove the catalytic converters from the listed Ferrari 348 and Mondial T exhaust layouts. Straight-through stainless sections create a louder competition exhaust and are a different choice from HJS sport catalysts. 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.
