Fabspeed Primary Cat Bypass Pipes for Ferrari F355 (1994–1999)

These Fabspeed competition pipes replace the F355 primary catalytic converters with straight stainless sections. They remove the primary catalyst elements and produce a substantially more exposed exhaust note. 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.
