Akrapovič Evolution Line (Titanium) + Tail Pipe Set (Titanium) - Porsche GT3 RS (991) 2014+

S-PO/TI/2/1 + TP-PO991RS/H/T

The titanium Evolution Line is a full system designed to give noticeably increased power at higher revs. With superb attention to detail, including parts cast in Akrapovič’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.

When installing Akrapovič aftermarket optional link pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory. When installing Akrapovič aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential »check engine light« warning signals.

Tailpipe Set (Titanium)

Top the system off with a pair of eye-catching double round tailpipes, made of high-grade titanium. Made specifically for the GT3 RS (991) version to withstand the higher temperatures at this distance from the bumper.

Akrapovič dB Reducer (Titanium)

Designed and constructed exclusively for the Porsche 911 GT3 (991) and GT3 RS (991), the Akrapovič 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 Akrapovič tailpipe set and then mounting the dB reducer in place. After installation, the Akrapovič dB reducer (Titanium) reduces dynamic sound levels* by approximately two or three decibels** while still retaining the unique Akrapovič sound and character. It is designed to fit and reduce the measured dynamic sound levels of all Akrapovič 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 Akrapovič dB reducer (Titanium) is also totally compatible with the optional Akrapovič carbon-fibre diffuser, which is available for the Porsche 911 GT3 (991).

The Akrapovič 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.
