Muffler sport Classic - Porsche 911 (997)

These mufflers fit on:

> All 997 3.6L and 3.8L

This exhaust is our sports version for the 997 phase 1. Its sound is intermediate between the original and our "Ultima Récital" version, it has the following characteristics:
> A good rant at the turn of the key
> Very discreet sound in stabilized mode
> His sport in accelerations
This muffler has been developed to be able to be fitted with 200cc sports catalysts, without it being too loud.
To be precise, the choice of the type of muffler is also made according to the engine cylinder capacity and also the type of gearbox.
All things being equal, a given exhaust will be quieter as the displacement increases. It is therefore more present with the 3.6L and smoother with the 3.8L.
The gearbox is even more discriminating. The Tiptronic gearbox, apart from the engine management settings which are different compared to a manual gearbox, makes the engine run at lower revs (compared to a manual gearbox).

We also have the following mufflers in our range:
> A super sound version "Ultima Récital" - (Reference: SCA 997 3 2 +) Best Seller
> A sports version with valve - (Reference: SCA 997 3 2 VI or VT)

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

This muffler is mounted directly after the catalysts.

The average installation time, including removal of the original exhaust, for this exhaust is 2.0 hours. Installation time may be faster if the exhaust to be removed is in good condition, but it may be longer if it is not. Removing the rear PC is not necessary, you just need to remove the bottom screws behind the wheels. If the sleeves to the catalytic converters and clamps to the outlets are original, it is best to replace them.

Using a lift is essential. Without one, you have to remove the computer, which will take twice as long.

The 4 screws on the 997 sleeves must be tightened to a torque of 46Nm. An exhaust that is not tightened enough can cause an air leak. But an exhaust that is too tight can also cause an air leak. And a leak at this level ruins the entire sound of the exhaust. The nuts must always be tightened gradually across all the nuts.

To ensure the best possible installation of all our exhausts, we include in the price of this exhaust a stainless steel screw mounting kit, all-stainless steel lock nuts and high-temperature copper grease. The connecting sleeves between the catalysts and the mufflers are not included in our mounting kit. We recommend that you use the sleeves designed for the 996; they are more robust. Apply copper grease to the screw threads and to the sleeves and clamps during installation.
