Central muffler - Super sound

This central muffler fits:

> All the 991

The sound of the 991 comes entirely from this central rear muffler, none from the lateral mufflers. This muffler without valves is very successful because it enables you to have a great sound when accelerating and decelerating yet remain discreet at cruising speed.  The version with valves offers a greater range of sound, but this one is excellent, and it's our favourite. Our mufflers for the 991 can be adjusted on one side which makes them easy to adapt.

Our range also includes:
> A sport version with valves - (Reference : SCA 991 3 2 VI or 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 catalyser outlets.

On average they take about 3 hours to fit, including the time it takes to remove the original exhaust. You will need to remove the rear bumper.  You will find the air filters here too, so we recommend that you take this opportunity to replace them with sport air filters.

It is preferable but not essential to use a car hoist as the original exhaust is fairly easy to remove. Remember that the bolts must always be tightened progressively across the whole set of bolts... When all is in place, tighten the clamp.

To ensure that our exhausts are fitted under the best conditions, a mounting kit including: gaskets, stainless steel bolts, stainless steel lock nuts, high temperature copper grease as well as the 2 straps, is included with the exhaust. We recommend using the copper grease on the bolt threads and the gaskets when fitting the exhaust.
