A winters morning time to take out Our very own Porsche 911 GT3 and RS (991 Gen 1 and 2) fitted with our Sport Side Muffler Deletes w/Valves (2014 on).

#QuickSilverExhausts

The original exhaust comprises a pair of manifolds, two catalysts and three silencers.

Plus, the OE system includes pneumatic valves that allow the owner to choose between two different volume levels, via the 'Exhaust Button'.

Manifolds / Headers

The standard manifolds are designed by German scientists with powerful computers - We doubt if they could be improved by an independent company.

Catalysts

Though imposed by international bureaucracy, the original catalysts are as efficient as possible. They are required for emissions regulations and warranty maintenance, plus their function & efficiency is programmed into the car's ECU. We recommend that these are retained.

Rear Silencer / Muffler

The standard rear silencer is extraordinary. It is one of those components of the rear-engined Porsche that has truly evolved and constantly improved since the 1940s. It is surprisingly lightweight and the internal design that encompasses two different paths (for the exhaust button) would also be extremely difficult to improve.

Porsche supply two version to the same design - only the material differs:

1) Thin-gauge Stainless for the GT3 & 911R and

2) Titanium for the RS (though the weight difference is minimal at 3 kilos).

The standard rear silencer includes an internal balance pipe that mixes the left & right cylinder banks to promote the best possible sound at higher rpm.
In Motorsport, most of the various Carrera Cup series retain this rear silencer for it's efficiency, light weight and rear crash protection.
Again, we recommend that the original silencer remains installed, especially if the owner wishes to retain full functionality of his 'Exhaust Button'.

Primary Silencers

The two primary silencers weigh 20 kgs (44 lbs). They fill the rear quarter panels and include the valve mechanisms for the 'Exhaust Button'.
The QuickSilver parts weigh 4 kgs - saving 16 kgs (35 lbs).
In fact, for the Carrera Cup motorsport cars Porsche Motorsport offer a similar kit to replace these silencers but... the Motorsport parts eliminate the functionality of the Exhaust Button, which is not required for Race Cars. See part #s 16 & 17 on the attached Porsche Motorsport parts diagram.

The QuickSilver parts suit all version of the Porsche 991 GT3 and, essentially, we include pneumatic valves to retain full function of the exhaust button.

There is now a much greater difference in sound when this button is pressed and 16 kilos is removed from the rear of the car. These are completely 'plug & play' and entirely reversible.

In developing our system, QuickSilver have consulted with Porsche GB's Motorsport arm to understand Porsche's options. We have also examined other aftermarket choices and performed thorough testing on our own 991 GT3.

We recommend our solution as the best and simplest option for the driver who seeks to reduce weight, to make a great car sound even better and still retain full functionality of factory exhaust button.

The QuickSilver kit is a straightforward parts replacement that requires no other modifications. Installation time is about 3 hours. We have this on our own GT3.
