Berk Technology 70mm Test Pipe w/ CEL Fix for 2000–2009 Honda S2000 BT1602

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.
