Turbo XS 2015+ Subaru WRX Front Pipe w/ Catalytic Converter - W15-FP-1C

If you want performance gains for your 2015+ WRX but want to keep a catalytic converter and don't want to spend a lot, this is the part for you. Replaces just the front pipe on your factory exhaust system with a higher-flowing 100 CPI metal substrate catalytic converter - the OEM pipe is the biggest restriction in your exhaust so replacing it has the biggest effect. All 16 gauge 304 stainless steel with 1/2 inch thick flanges polished to a beautiful finish.
