This European Pre-Muffler Catbypass Pipe is brought to you by FabSpeed for your Porsche. All 964 C2/C4/RS America products 1989-1994 +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. Just like Porsche factory German catbypass Euro-premuffler but without the $700.00 price. 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.
