TurboXS Subaru WRX & Sti (02-07), Forester XT (04-08) High Flow Catalytic Converter Pipe

The TurboXS 200 cell metal matrix catalytic converter was designed to keep a high flow of exhaust gases while still having the ability to catalize properly. This pipe is NOT a replacement for the factory catalytic converter and can only be used only with the our exhaust components. Use with Original TurboXS Downpipe (WS-DP) and Midpipe (WS-MP) to make a Stealthback Exhaust and add any one of our mufflers to that to make a complete Turboback Exhaust.
