Sport Highflow Catalytic Converter
A high-flow replacement catalytic converter for the Porsche 964 Carrera (1989-1994), a direct bolt-on for cars whose original converter has failed, been gutted, or gone missing over the car's now 30-plus years. Dyno testing showed gains of 28 hp and 16 lb-ft of torque across the rev range, with a louder exhaust note and no interior An unwanted droning resonance at certain highway rpm, where exhaust pulses match the cabin's natural frequency.. Built from 14-16 gauge CNC mandrel-bent T304L stainless steel, it's OBD2 certified and EPA compliant, and Fabspeed guarantees no catalyst-triggered check engine light. Installation is a simple DIY bolt-on. Rennen Motorsport or an authorised dealer can also fit it, for owners who'd rather not do it themselves.
