  1. Excellent 5 Star Review

    Posted by on 1st Oct 2016

    You can feel that the car is more responsive. Definitely a great new sound. My 964 Passed emission inspection with ease as the numbers were well below the states requirements

  2. 800 miles including AutoX 5 Star Review

    Posted by on 2nd Sep 2014

    Alright, I installed the Fabspeed exhaust about a week ago and put about 800 miles on it already, including an AutoX.
    The shipping was a lot faster than expected, the fitment is outstanding.

    In the beginning I was concerned about the not existing heat shielding, nevertheless I have the feeling that the temperatures in the left wheel well are now cooler as they were before.

    It feels like that the car revs up a little bit more freely, especially above 4000 rpm.
    The sound is definitely more aggressive, but at the same time not really much louder.

Product Description

High-flowing, direct bolt-on replacement for the bulky & restrictive factory catalytic converter


Why We Choose HJS Catalytic Converters: 


HJS German imported catalytic converters are made from some of the highest grade material you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.                                                                       


  • Fits all Porsche 964 C2, C4, RS America, Euro RS and Speedster vehicles 1989-1994
  • Increases horsepower and torque by 24 wph and 16 ft-lbs for greatly improved throttle response
  • Less back pressure and improved throttle response
  • Constructed from 14-16 gauge, T304L C.N.C. mandrel bent stainless steel
