Fabspeed Competition Pipe and ECU Package for Mercedes-AMG G63 (2019–2024)

This G63 package pairs secondary catalyst-delete pipes with the XperTune software specified for the installation. The exhaust requires cutting at the original inlet pipes, so it is not an untouched-factory-pipe swap. 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.
