Bursch High-Flow 300 Cell Catalytic Converter Porsche 911 Carrera (1976-1989)

For decades, Bursch has been helping Porsche enthusiasts get more enjoyment from their air-cooled 911s through thoughtfully designed exhaust systems that improve performance while preserving the character of the car. The Bursch High-Flow 300 Cell Catalytic Converter continues that tradition.

Hand-built in Pasadena, California, this direct-fit catalytic converter replaces the heavy, restrictive factory unit with a modern high-flow design that allows your engine to breathe more efficiently. The result is improved throttle response, reduced weight, and a subtle increase in the distinctive flat-six exhaust note that makes the air-cooled 911 such a rewarding car to drive.

Constructed from premium mandrel-bent T304 stainless steel, this catalytic converter is designed for years of reliable service and corrosion resistance. An integrated oxygen sensor bung accommodates fuel-injected models, and all necessary installation hardware is included for a straightforward bolt-on installation.

Whether you’re restoring a classic Carrera or simply looking to improve the driving experience, this high-flow catalytic converter delivers modern exhaust technology while respecting the timeless character of your Porsche.
