Fabspeed Secondary Competition Pipes for BMW M5 (F90, 2017+)

These secondary catalyst-delete pipes are a separate competition upgrade from the F90 M5 primary downpipes. They replace the downstream secondary catalysts at the original-style connections. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for sports cars including Porsche. Its development work uses dynamometer testing, road evaluation and racetrack testing.
