Catalytic Test Pipe


      • Porsche 911, 911SC 3.0 L, and Carrera 3.2 Models from 1974-89. Models 1974-79 use bolt in the O2 sensor bung to close off the O2 bung for early models.
      • Our Pipe includes a new set of gaskets for both end connections of the test pipe.
      • Bolt-on for driver’s schools and race events or to test your catalytic converter. Off-road use only!
      • It increased horsepower, torque, and sound. It has about 10 HP more and a better throttle response.
      • Manufactured out of T304 Stainless steel and polished for an excellent look.
      • The design has bulged in the center to mimic the shape of a catalytic converter to closely simulate the air flow.  (will not pass smog test)
      • Includes O2 sensor bung so your fuel injection system continues to operate correctly and can continue to adjust the mixture for maximum performance
