This product is crafted from high-grade, lightweight titanium for a weight reduction of 45% (14.5 kg) compared to the sport stock exhaust. This exhaust system features a central muffler with valves on both sides ‒ with valve housings cast in-house ‒ to regulate the gas flow before it exits through two pairs of attractive double round handmade carbon-fibre tailpipes that contain acoustic reflectors to deliver enhanced sound to the passenger cabin. A comfortable sound with a pleasant V8 back track is emitted at cruising speed, which becomes sportier when driven more dynamically and through the use of the car’s mode selectors. When tested on the Akrapovič dyno against a Porsche Cayenne Turbo E-Hybrid with a stock sport exhaust system, it achieved a power gain of 4.0 kW (5.4 hp) at 2,100 rpm and a torque increase of 18.6 Nm at 2,050 rpm. This product has plug-and-play installation and no need for remapping.

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.

Fitment Notes: This Evolution Line (Titanium) does not fit on Cayenne GTS Coupé with optional Sports exhaust system with central tailpipes. This system does not fit on model Cayenne Turbo E-Hybrid Coupé with GT-Package.

With the use of the optional Akrapovič Sound Kit, the ECE type approval of the Evolution Line (Titanium) is no longer valid.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.

Further control over the sound of the Evolution Line (Titanium) exhaust system can be achieved by installing the optional Akrapovič Sound Kit. This gives the occupants of the car the option to regulate the exhaust tone by switching between the quiet mode and a sportier sound. This is facilitated through the use of a Sound Remote Controller or the smartphone app (for iOS and Android), which regulates the valves to drive the actuators that open or close them through the use of a receiver in the system.

When fitted with the optional Akrapovič Sound Kit, ECE type approval is no longer valid.

Fabspeed's Sport Catalytic Converters replace the restrictive factory cats with high-performance German-imported 200-cell HJS catalytic converters for significantly improved performance and sound. The Cayenne's factory cat-back exhaust has a very free flowing design when the valves are open so the only way to gain more sound and power is to change out the factory catalytic converters. HJS Sport Cats flow extremely well, flowing at 93 - 95% the rate of a straight pipe. Fabspeed Motorsport invested a lot of time and resources into developing the best possible downpipes and we're now proud to offer you this latest and greatest solution.

SOUND:
Aside from the factory catalytic converters, the E3 Cayenne GTS / Turbo has an extremely free flowing exhaust. So the best way to get more sound out of your Cayenne is to replace the factory catalytic converters. These Sport Cats will make your Cayenne sound much more aggressive. It really brings out the V8 sound from the 4.0L powerplant. Pops, bangs and crackles will be much louder and sharper. Best of all, there is no interior drone whatsoever.

POWER:
Get awesome bolt on power gains from your Cayenne GTS / Turbo with these Sport Cats. We saw max gains of 22 whp and 21 ft/lbs of torque. These Gains are carried throughout the entire RPM range for power you can feel in the seat of your pants. Peak power is also up 12 whp and 4 ft/lbs of torque!

Product Details:

There is no guarantee this will prevent a CEL from triggering

Universal O2 spacers with real precious metal Catalytic Converters lengthen the distance between the O2 spacer(s). We've taken our spacers a step further by having built-in catalytic converters to allow the ECU to properly read exhaust gas and perform at optimal performance.

Oxygen sensors can occasionally trigger a CEL on stock vehicles due to the new advances of technology and would require an O2 spacer to bring the vehicle back to equilibrium and allow the ECU to read exhaust gases within the proper threshold.

FEATURES:

• Fits most makes & models worldwide (Specify Angle option from drop down above and Quantity needed for your specific vehicle)
• Spacer available in a 90 Degree
• Male end threads into existing M18 x 1.5 O2 Bungs
• Spacer body dimensions: 3 3/4" L x 1 1/2" W x 1 1/2" H
• Fitting dimensions: 1" L x 1" W x 1" H (not including threaded portion)
• 1" depth of threads on fittings for adjustments

NOTES:

• For use on DOWNSTREAM oxygen sensors only
Universal fitment for all cars
• For off road competition use only, not to be use on public roads or highways. Please check with your local authorities to ensure compliance with all laws.
• There is no guarantee this will prevent a CEL from triggering, please contact a Fabspeed Performance Specialist for more details.

Product Details:
Universal O2 Spacers with Catalytic Converters scrub the exhaust and lengthen the distance between the O2 sensor(s) and the exhaust flow to reduce the chance of a CEL.

We've taken our O2 spacers a step further. The factory ECU compares the readings from a pair of oxygen sensors to measure the effectiveness of the catalysts. When a high-flow cat or catbypass pipe is used the exhaust gases reach the O2 sensor faster and uncleaned, leading to high chances to throw a CEL. Our O2 spacers retract the secondary oxygen sensors from the direct flow of gases, restoring the balance that the ECU requires when using aftermarket catalysts or catbypass pipes. The high quality built in catalysts scrub the exhaust to further reduce the chance of a CEL. Two fitting options and the two piece design allow for adjustment to get best possible fitment and results.

FEATURES:
Fits most makes & models worldwide
Compatible with all Fabspeed Motorsport header, Sport Cat, and Catbypass products
Minimizes the triggering of the CEL by moving the O2 sensor further from the exhaust stream and scrubbing exhaust
