TECHNICAL DATA

** measured with: Porsche Cayenne Turbo / Coupé (536) - OPF/GPF 2019

Maximum power:
- kW: + 8.2 / 5600 rpm
- HP (m): + 11.1 / 5600 rpm

This stunning system is constructed entirely from lightweight high-grade titanium. Its beautiful and sleek design is finished with a central muffler with two pairs of eye-catching double round tailpipes – available in either handmade carbon fibre or sandblasted and coated titanium for increased durability – and it incorporates exhaust-valve housings cast in the Akrapovič in-house foundry. The sound has been tuned to deliver a fulfilling acoustic statement every time the car fires to life. The Evolution Line (Titanium) produces a deep, strong growl from the V8 turbo engine, giving the driver and passengers a true feeling of the immense torque the engine has to offer. This is achieved through a carefully designed X-crossing element in the link pipes that influences the sound. This allows the exhaust gases to mix from both sides of the engine, placing the resulting combination on par with a finely tuned musical instrument and creating incredible high-frequency overtones as the revs rise, all without any compromise to aural clarity and comfort. Fully ECE-compliant and with a simple plug-and-play installation, with no need to remap the ECU, the Evolution Line (Titanium) also adds increased performance to the stunning visual appeal. Test gains achieved by the Akrapovič technicians in controlled conditions show both power and torque gains over the Porsche sport exhaust system of +8.2 kW at 5,600 rpm and +16.6 Nm at 2,400 rpm, respectively, making the system an impressive addition to the Porsche Cayenne Turbo (536).

The sound can be further controlled with the addition of the optional Akrapovič Sound Kit, which offers increased operational features over the exhaust system. When fitted with the optional Akrapovič Sound Kit, ECE type approval is no longer valid.

ECE type approval is only valid for cars equipped with otto/gasoline particulate filter.

Fabspeed's Cat Bypass Pipes replace the restrictive factory cats with straight pipe zero restriction pipes for significantly improved performance and sound. Porsche is constantly updating and revolutionizing their vehicles and offering even better performance, and we're dedicated to doing the same. Fabspeed Motorsport is the world's authority for aftermarket Porsche performance.

FEATURES:
• Fits all Porsche E3 Cayenne GTS / Turbo Vehicles (2019+)
  Cat bypass pipes with 5” to 3” long gradual transition for the best flow possible
  Saves 13.4 lbs / 6 KGs compared to the stock catalytic converters
  CNC machined flange for perfect OEM fitment
  Fabspeed Motorsport USA recommends HJS German highflow catalytic converters for all other usage as they flow 93% of a straight pipe and outperform cat bypass pipes.
  Constructed from mandrel bent T304L stainless steel
  Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required
  All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

SOUND:
Aside from the catalytic converters, the E3 Cayenne has an extremely free flowing exhaust. So the best way to get more sound out of your E3 Cayenne is to replace the factory catalytic converters. These Cat Bypass Pipes will make your Cayenne incredibly rowdy. Pops, bangs and crackles will be gunshot loud. This will be at the cost of some interior drone.

DISCLAIMER: This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product is or contains a Racing Cat Bypass Pipe, which will give you check engine lights on OBD2 cars. Racing Cat Bypass Pipes are solely intended for track and race cars as they are NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.

Fabspeed Sport Catalytic Converters. 

FEATURES:

•  Fits Porsche E3 Cayenne GTS / Turbo / Turbo GT / Turbo S E-Hybrid 4.0L Twin Turbo V8 vehicles (2019+), and 2024+ Cayenne S
•  The largest catalytic converter that will fit the application
•  German Imported HJS 200 Cell High Flow Catalytic Converters
•  Saves 6 lbs / 2.7 KGs compared to the factory Catalytic Converters
•  Adds 22 WHP and 21 ft/lbs of torque

•  Constructed from mandrel bent T304L stainless steel
•  Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required
•  All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

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!

Porsche 9YA Cayenne GTS / Turbo 4.0L TT 2019>> SOUL Cat Bypass Pipes

Cat Bypass Pipes replace the restrictive factory catalysts with free flowing straight pipes to unlock an invigorating increase in turbo sound, engine note, and throttle response. Revel in the new sensation of sounds as the turbos sing and exhaust crackles on deceleration.

  Fits all Porsche Cayenne (9YA) GTS / Turbo / Turbo S / Turbo GT vehicles with 4.0L TT (2019+)
  Weighs approximately 12 lbs / 5.4 kg less than factory exhaust components (10 lbs vs 22 lbs)

DEVELOPMENT:
Looking to unleash more power—or make your presence known? The SOUL Cat Bypass Pipes eliminate the restrictive factory catalytic converters to achieve the highest possible exhaust flow and performance. Engineered to support significant power increases, these pipes enhance turbo response and drivability while adding the crisp pops and turbo sounds worthy of a high-performance SUV.

CONSTRUCTION:
Each pipe is handcrafted from mandrel-bent .065″ wall, 3″ diameter T304L stainless steel tubing with precision CNC-cut flanges for a perfect seal. All welds are back-purged to ensure superior strength and longevity, even under extreme heat and pressure.

BOLT-ON INSTALLATION:
Every set is fixture-built and test-fitted for guaranteed perfect fitment. Each unit undergoes rigorous quality inspection before being foam-packed for secure shipping. The kit includes new high-grade hardware for seamless installation to the existing exhaust system.

CHECK ENGINE LIGHT:
Because these pipes remove the factory catalytic converters, a check engine light may occur. For off-road or track applications, we recommend an ECU tune to disable any CEL warnings.

Fabspeed Universal 45 Degree O2 spacers with catalytic converters, Pair.

fabspeed

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
