Fabspeed European Pre-Muffler Catbypass Pipe with Gaskets

Features:

Fits: 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.
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.
