964 European Pre-Muffler Catbypass Pipe



    * All 964 C2/C4/RS America products 1989-1994
    * Copper gaskets included.
    * +12HP & more torque.
    * High Quality T304 Stainless steel mirror polished showcar shine
    * O2 sensor bung so your 964 fuel injection system can automatically adjust mixture/idle/part throttle for maximum performance.
    * LOOKS like a stock catalytic converter--best way to pass a visual exam inspection but the system straight “see through” with an internal muffler inside.
    * Simple and easy bolt on installation.
    * Quieter and more durable than a mild steel straight pipe yet you can still roll a golf ball thru the Fabspeed pipe!
    * Catbypass & Fabspeed sport exhaust makes more horsepower than virtually any aftermarket exhaust system.
    * Best PROVEN performance value on the market.
