Fabspeed Catalytic-Converter Re-Coring Service for Porsche GT3 Cup

This is a service to renew the catalyst core inside an existing Porsche GT3 Cup exhaust housing. You must supply the original catalyst assembly; it is not an off-the-shelf replacement exhaust or a complete catalyst set. 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.

Before you order

Arrange the re-coring service with PMB before ordering or shipping a converter. Confirm the accepted original housing, replacement core, number of converters included, shipping and turnaround. This is a service, not a new complete converter assembly.

Use restrictions
