Prodrive Center Pipe Subaru WRX STI 02-05

This pipe replaces the last catalytic converter on the WRX and STi. Reduced exhaust backpressure increases horsepower and torque and also increases engine response. High quality bends and welds, what you'd expect from Prodrive. Direct replacement for the stock pipe. Will bolt to any exhaust that bolts to the stock "last cat pipe". Off Road Use Only
