Product Description

The Turbo XS WS02-CP High-Flow Catalytic Converter Pipe is a performance exhaust upgrade engineered for turbocharged Subaru WRX (2002-2007), WRX STI (2004-2007), and Forester XT (2004-2008) models. Its 3" diameter 304 stainless steel construction provides smoother exhaust flow compared with the stock catalytic converter, reducing backpressure and helping improve throttle response and power delivery. Integrated oxygen sensor bungs make it compatible with factory and wideband sensors for accurate air/fuel management and tuning.

This high-flow catalytic converter pipe is designed to bolt directly into Turbo XS downpipes or other compatible exhaust components, and it works with most aftermarket cat-back systems for a complete performance exhaust upgrade. While helping maintain emissions compliance in many regions, the WS02-CP balances performance gains with practicality, making it a strong choice for enthusiasts who want enhanced flow and exhaust tone without sacrificing street legality in supported areas.
