Valves - Switch

These mufflers only fit the:

> 997 3.8L Sport Classic and Speedster (switch controlled)

Porsche do not have a sport exhaust option for these exceptional cars.  The principle of an exhaust with valves is that you have a choice between a discreet sound and a very sporty sound at the flick of a switch. With the valves closed, the sound is a little more present than the original, and with the valves open the sound becomes very sporty.  All the accessories are included (wiring harness and air kit). For these two cars this exhaust can only be fitted at our workshop, just north of Paris.

Our range also includes the following mufflers:
> A sport version with valves (remote controlled) - (Reference : SCA 997 SC 3 2 VT)

Our exhausts all fit onto the original interfaces.  By this we mean their entry, their outlet and their size are the same as those of the original part.

These mufflers fit straight onto the catalytic converters.

On average it takes about 8 hours to fit, including the time it takes to remove the original exhaust. It will be faster if the exhaust we're removing is in good condition, just as it may take longer if the reverse is true.
