Free up exhaust flow and sharpen your S2000’s performance with the Berk Technology 70mm Test Pipe. This upgrade replaces the factory catalytic converter with a large 70mm (2.75") straight-through test pipe, helping your engine breathe easier. It also features a built-in O2 sensor CEL fix designed to reduce the chances of a check engine light (CEL) after installation.

Built from full 304 stainless steel, this test pipe is made to handle heat, resist corrosion, and hold up to long-term use—especially in demanding track environments.

Key Features

Performance Benefits
