Akrapovic Race Line Exhaust System for Porsche 911 GT3RS (991.2)

SO - Slip-On

Slip-on system (S-PO/TI/15) for GT3 RS / Speedster OPF model must be mandatory combined with:

• Evolution Header Set (E-PO/T/6/1)
• Tail pipe set TP-T/S/19. 

When combining the slip-on system with optional carbon fibre diffuser DI-PO/CA/7/G, you must use tail pipe set TP-T/S/17.- An additional original Porsche stock bracket (Porsche p/n: 99111147391) is required for mounting the Akrapovic exhaust system. 

Please read the instructions carefully before the start of the installation.This Slip-On Race system (S-PO/TI/8) must be upgraded into a full Akrapovic Evolution Race Line exhaust system by combining it with the Evolution Header Set (E-PO/T/6) with side mufflers and valves, which is designed to supplement the performance at higher revs.

With complex parts cast in Akrapovic’s own titanium foundry, the expertise used in this system, and the coating finish, the system demonstrates the highest standard of workmanship and technology. Incorporating 100 cpsi sports catalytic convertors in the exhaust manifold and side mufflers, the Evolution Race Line utilizes integrated catalytic convertors and the functionality of the exhaust valves to deliver a complete workout for the senses. The system offers a near-perfect power curve, along with an altered torque distribution, all designed to continually deliver performance as the revs rise. The use of lightweight materials results in big weight savings, and the addition of the Evolution Race Line will have the car performing like a true cup racer, with a powerful racing sound that resonates with every push of the accelerator pedal, producing a deep, pure racing growl to match the performance

The mandatory tail pipe set TP-T/S/19 needs to be ordered separately.

PERFORMANCE:

Evolution Header Set converts the slip-on system into a full  Evolution Line system designed to give noticeably increased power at higher revs. With superb attention to detail, including parts cast in Akrapovic’s own titanium foundry, the craftsmanship and coating finish on the system is a joy to behold.

With a newly developed exhaust manifold, incorporating 100 cpsi sports catalytic convertors and side mufflers—all designed to increase power and torque—the Evolution Line utilizes integrated catalytic convertors and the functionality of the new exhaust valves to deliver an out-and-out attack on the senses. With the valves in the open position, the Evolution Line sounds like the top-performing Evolution Race system, but also has the option of a lower sound level when the valves are closed, perfect for use in more everyday locations. Offering an increased weight savings in the area behind the engine and the rear axle, the reduction will enhance the handling and improve performance.

The Evolution Line is also tuned to deliver a sportier and hard-hitting sound—in open valve mode, the more the engine is revved the better the sound gets—as well as increasing performance, all to provide an even greater sensory experience. With the addition of the handcrafted high-quality optional carbon- fibre rear diffuser, the Evolution Line will show that the GT3 means business even when it’s standing still.

The system offers a perfect power curve right from 3,000 rpm to the very top of the power band, designed to continually increase performance as the revs rise. Along with improved torque and the maximum weight savings to enhance handling, the Evolution Race Line exhaust system will have the car performing like a true cup racer—with a deep, loud, and powerful Akrapovic racing sound to match its performance.

The assault on the senses from the Evolution Race Line system can be boosted even further with the addition of the perfectly handcrafted optional carbon- fibre diffuser. Made exclusively for the Porsche GT3, this beautiful add-on will make a statement both on and off the track.

Designed and constructed exclusively for the Porsche 911 GT3 (991) and GT3 RS (991), the Akrapovic dB reducer (Titanium) is aimed at driving enthusiasts who need to keep the noise of the exhaust within approved levels during track-day use.

Made from high-grade lightweight titanium, the dB reducer works like an additional muffler to allow extra expansion of the exhaust gases. It is easily fitted by simply removing the Akrapovic tailpipe set and then mounting the dB reducer in place.

After installation, the Akrapovic dB reducer (Titanium) reduces dynamic sound levels* by approximately two or three decibels** while still retaining the unique Akrapovic sound and character. It is designed to fit and reduce the measured dynamic sound levels of all Akrapovic systems for the Porsche 911 GT3 (991) and GT3 RS: the Slip-On Line (Titanium), Evolution Line (Titanium), Sports Cup Line (Titanium), and Evolution Race Line (Titanium).

The Akrapovic dB reducer (Titanium) is also totally compatible with the optional Akrapovic carbon-fibre diffuser, which is available for the Porsche 911 GT3 (991).The Akrapovic dB reducer (Titanium) fits also to the stock exhaust system of the 911 GT3 (991) and GT3 RS (991);

Dynamic sound levels apply to a moving vehicle and not the volume from a static vehicle.**Noise reduction value is relative (or may vary) due to various noise-measuring methods used and external conditions at different racetracks.
