Porsche 911 Carrera 993 3.6 Valved Exhaust System (1994-1998)

The Porsche 911 Carrera 993 exhaust in detail.

The whoosh of the fan, the metallic grain of the opposed cylinders, then a hoarse rumble that hardens at high revs: the 993, the last air-cooled 911, has a voice nothing can imitate. Its factory exhaust, designed for 1990s comfort, keeps most of it to itself. With the valves open, the Rog valved cat-back gives the flat-six a more present idle and a climb through the revs full of texture; with the valves closed, the car stays discreet for long journeys and town.

The system is for the 993-type 911 Carrera with the 3.6-litre engine, 272 hp and 330 Nm in its original specification, before the Varioram variable intake enriched it, for the 1994 to 1998 model years. The Carrera S is not yet documented in our records: for that car, and for any 993 with a particular history, we use your VIN to check compatibility before manufacturing.

This page sells the system alone, without a front section: it fits after the factory front section, which you keep. No welding or cutting, which matters on a collector’s car: band clamps, gaskets, about two hours on a lift. The valves are controlled by the Rog remote, with its box in the boot, or by a factory control if your car has one.

The choice of material follows the use: 304 stainless steel, with its full, round sound, resists salt and damp, while titanium weighs around 40% less for the same design and sounds more metallic at high revs, in brushed, gold or purple. The tips, for their part, come in chrome, gloss black or blued titanium, from the most understated to the boldest.
