Sport Performance Pre-Muffler for Porsche 911 (2.7L, 3.0L, 3.2L)
Unleash the full potential of your Porsche 911 (2.7L, 3.0L, 3.2L) with our sport pre-muffler. Designed specifically for these models, it corrects the pressure losses of the original parts, ensuring linear exhaust gas compression and allowing your engine to deliver its rated power.
This sport version optimizes gas flow while maintaining a sound level comparable to the original, offering a high-performance replacement without significantly altering the sound of your vehicle.
Simplified installation: Mounted between the manifolds and the muffler, this pre-muffler respects the original interfaces for direct, modification-free installation. A complete installation kit is included, including all-stainless steel gaskets, screws and lock nuts, as well as high-temperature copper grease, for quick and efficient installation (approximately 1.5 hours).

> 911 3.2L
The pre-muffler is the most technical part of the exhaust line for these cars. Our 5 pre-mufflers correct the defects of the original part, namely essentially the pressure loss due to the flow which disrupts the back pressure. Our exhausts allow the engine to release its nominal power thanks to linear compression of the exhaust gases.
This sport version of the pre-muffler allows for better gas flow. It has a sound level comparable to the original, allowing this part to be replaced without adding more sound.
We also have the following pre-mufflers in our range:
> A standard catalyzed 400cc version - (Reference: SCA 911 2 1 CAT)
> A 100cc catalyzed sports version - (Reference: SCA 911 2 2 CAT)
> A sports version - Riva-type sports sound - (Reference: SCA 911 2 2 RIVA)
> A racing version - super sound - (Reference: SCA 911 2 3)
Our exhausts all have the original interfaces, meaning that their inlets, outlets and dimensions are consistent with the original part. They can therefore be fitted in place of the original part without any modification.
This pre-muffler is mounted between the collectors and the muffler.
The average installation time, including removal of the original exhaust, for this exhaust is 1.5 hours. Installation time may be faster if the exhaust to be removed is in good condition, but it may be longer if the opposite is true.
The use of a lifting bridge is preferable but not essential.
Removing the stock exhaust can be tedious and requires specific tools, such as a micro grinder to remove the pre-muffler inlet nuts. For easier disassembly, we recommend removing the wheel and the left rear shock absorber.
Tightening the nuts should always be done gradually over all the nuts. Ensure that the muffler is securely in place before tightening it completely.
To ensure that all our exhausts are fitted in the best possible conditions, we include in the price of this exhaust a fitting kit with gaskets, stainless steel screws, all-stainless steel lock nuts and high-temperature copper grease.
