- Made entirely from lightweight, high-quality SS304L stainless steel for durability, corrosion resistance, and long-term reliability — ideal for spirited driving or restoration builds.
- Designed for “TÜV” compliance (option with catalysts), while delivering a more aggressive exhaust note, improved throttle response, freer revving and performance gains compared to stock exhaust. cargraphic.de Reduced back-pressure and optimized flow — leads to smoother engine breathing, potential gains in horsepower/torque, more immediate throttle response and enhanced driving dynamics.
- Upgraded mounting hardware, mandrel-bent pipes and optimized geometry ensure correct fitment, easy installation (with included gaskets, clamps, brackets), and good clearance to engine components.
- Lightweight construction also contributes to modest weight savings compared to stock exhaust components — beneficial for handling and responsive driving.
Why Choose This Exhaust System?
The original exhaust on older 964 models can be restrictive in flow, heavy, and produce a muted sound. Switching to this CARGRAPHIC system unlocks the engine’s full potential: better exhaust flow, sharper throttle response, more pronounced exhaust tone, and improved performance — all while retaining reliability and proper fitment. It’s an ideal upgrade for enthusiasts seeking classic 964 sound and performance without resorting to race-only systems.

This product is constructed from high-grade lightweight titanium featuring a central muffler with two pairs of striking double round handmade carbon-fibre tailpipes, which contain acoustic reflectors, designed to enhance the sound experience for both the driver and passengers. The valves on both sides of the muffler control gas flow, with housings cast in-house. The weight is 44.8% (14.6 kg) lower than the sport stock exhaust. A power gain of 4.2 kW (5.7 hp) at 5,950 rpm and torque increase of 8.0 Nm at 2,150 rpm were achieved when tested on the Akrapovič dyno against a Porsche Cayenne S E-Hybrid Coupé with a stock sport exhaust system.
The harmonic and satisfying sound, perfectly matched to the engine’s operation, gives the impression of a V12 engine from inside the cabin. The specially developed control kit converts the Akrapovič exhaust system from a mechanical system to a mechatronic one. The gas flow from each link pipe is driven into the muffler without unpleasant streaming or whistling, with peaks at specific frequencies dampened for cruising comfort, and the sportier and emphasized sound is fully embraced when driving more dynamically. The sound experience of the Evolution Line (Titanium) system is directly linked to the car’s drive with no compromise to comfort or sportiness. This product is ECE type approved, with plug and play installation and no requirement to remap the ECU.
An optional Akrapovič Sound Kit is available, which will increase the aural pleasure of the Akrapovič Evolution Line (Titanium) exhaust at lower revs and further supplement the sound as the revs rise.
For mounting Akrapovič exhaust S-PO/T/2 or S-PO/T/3H on Porsche Cayenne (base V6) models without Porsche sport exhaust, additional wiring kit P-HF1621 has to be bought.
With the use of the optional Akrapovič Sound Kit, the ECE type approval of the Evolution Line (Titanium) is no longer valid.
The Evolution Line (Titanium) exhaust system is ECE type approved for cars equipped with Otto/gasoline particulate filters.
