Evolution exhaust system for Porsche 911 GT3/RS/RS 4.0 (997 FL)

Performance

The weight distribution of the vehicle is improved considerably, because of that weight reduction in the area behind the engine and the rear axle, which has a positive effect on the handling. The limit range of the vehicle adjusts upwards and so a higher transverse acceleration is possible. The combination of improved power to weight ratio (through an increased efficiency of 12 HP*), torque progression by 14 Nm*, and the positive effects in connection with driving dynamics enhance the performance of the GT3 distinctively. The sound impression in this configuration is somewhat more voluminous and with opened caps way more aggressive than in the original version.

Evolution system:

• titanium sports manifold system with integrated 100 cpsi catalysts
• titanium pre mufflers
• titanium link pipes with exhaust valves
• titanium end muffler
• titanium tail pipes

Hard facts:

• plus 12 HP* (at 5.510 rpm)
• plus 14 Nm* (at 5.740 rpm)
• minus 17 kg*

Optional:

• rear carbon fiber lip

When fitting Evolution system we strongly recommend the usage of the optional rear carbon fiber lip to avoid any possible heat damage to the rear bumper.

* Please note hard facts of updated systems are comparable to 997 GT3/RS Akrapovič aftermarket system and therefore all data is preliminary.

Please note rear carbon fiber lip is mandatory.

When installing an aftermarket Akrapovič Evolution exhaust system, which is developed for use on closed track, we recommend remapping of the ECU to prevent possible “engine check light” warning signal.
