Valved Exhaust - Porsche 911 (993)

These silencers can be mounted on:

> All 993

On the 993, the muffler accounts for 80% of the sound level (the remaining 20% comes from the catalytic converter). This valved version allows you to choose between a discreet sound or a very sporty one. The valve action is controlled by a switch on this model. You can also choose the remote control option if you prefer. When paired with a sports catalytic converter, the sound becomes incredibly powerful with the valves open.

We also have the following silencers in our range:
A sports version - (Reference: SCA 993 3 2)
A RIVA version - (Reference: SCA 993 3 2 RIVA) Best seller

Our exhausts all have the original interfaces, meaning that their inlets, outlets and dimensions are identical to the original part.

These silencers are mounted directly after the catalytic converters.

The average installation time for this exhaust system, including removal of the original exhaust, is 8 hours. Installation may be faster if the existing exhaust is in good condition, but it may take longer otherwise. Removal of the rear bumper is not required. This time also includes the installation of the air and electrical wiring harnesses.

Using a lift is essential because the mufflers are removed from underneath. The nuts must always be tightened gradually, one at a time.

To ensure the best possible installation of all our exhaust systems, we include a mounting kit with stainless steel screws, stainless steel lock nuts, and high-temperature copper grease in the price of this exhaust. If your original mufflers are Gillet style, you will need to purchase two olive washers and two Bischoff muffler clamps from Porsche. We recommend applying copper grease to the threads of the screws and to the olive washers both upstream and downstream of the mufflers.
