Akrapovic Evolution Line Titanium Exhaust

Fits:
Porsche (971) Panamera GTS / Sport Turismo 2019 - 2020
Porsche (971) Panamera Turbo / Sport Turismo 2017 - 2020
Porsche (971) Panamera Turbo S E-Hybrid / Sport Turismo 2017 - 2020

This stunning system is made completely from high-grade titanium. It includes parts cast in the company's in-house foundry, featuring an active X connection and an additional pair of exhaust valves behind the rear mufflers, designed to provide optimal control of the exhaust sound for the best aural enjoyment. The system has been perfectly tuned to deliver the very best sound experience in all modes – enormous effort was invested to give it a sporty, deep higher-frequency V8 sound with an unmistakable Akrapovič character, while keeping it smooth and eliminating any drone for maximum everyday comfort. By using the optional Akrapovič Sound Kit, the driver can choose between a loud racy sound or a quieter note for long-distance driving, regardless of the mode chosen for the vehicle. The look of the Evolution system can also be further enhanced by adding four round titanium or carbon-fibre tailpipes.

An increase in performance and torque through a broad rpm range and a significant weight savings of 40% makes this a very serious performance upgrade. With optimized gas flow and reduced back pressure, it allows limitless tuning options.

Because it is ECE type approved with no need to remap the ECU or add any other parts, it is just a simple plug-and-play installation. The exquisite Akrapovič Evolution Line (Titanium) exhaust system adds performance and style, along with an amazing soundtrack.

With the use of the optional Akrapovič Sound Kit, the ECE type approval is no longer valid.

For vehicles with the base (non sport) Porsche exhaust system, which is then replaced by the Akrapovič Evolution Line system, the Middle Valve Actuator Kit (P-HF1170) is a mandatory upgrade.

Fittment notice: This system does not fit on vehicles equipped with Otto particulate filter (OPF). This product will not fit on Executive models.

The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovič technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver (already included in evolution system) to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves.

With the use of optional Akrapovič Sound Kit, the ECE homologation is not valid anymore.

Product Information
Product Information
You know the problem: modern engine control units can react to even the smallest changes to the system and register fault codes.

With the OBD killer we have created a universal solution.
The device cyclically checks for pending and permanent error codes and deletes them.

Error codes or entire classes can be isolated on request.
If an error occurs outside of the expected error classes, the deletion process stops.
Thus, the functionality of the fault memory is maintained.

We present the new generation of the OBD Killer

Teachable
The new OBD killer learns the entered error codes and is therefore suitable for all emission-related, sporadic errors

Automatically
While driving, the engine control unit is monitored for sporadic errors in real time

Fast
Already existing error codes are blocked
Even before an error message is entered

Universal
For almost all vehicles from 2008
(some earlier cars may be supported)

What is the OBD Killer?

"OBD" stands for "on-board diagnostics", the standardized diagnostic interface of motor vehicles.
The OBD Killer is a compact electronics module, which is simply plugged into this diagnostic port.
There it will monitor the error messages of the engine control unit in real time for possible entries.
If a pending error is detected in memory, the OBD Killer blocks it before the driver sees a message on the Instrument Cluster/Check Engine "MIL" is Illuminated.

As soon as there is an error messages of no concern registered, the OBD Killer intervenes immediately,
removes the pending error message before it comes to an entry in the actual fault memory.
If an error code has already been entered before using the OBD killer, it will also be removed.

For which vehicles is the OBD Killer suitable?

The OBD killer can be used on all vehicles from model year 2008.
There are also vehicles that already support the necessary standard in the years before.
These vehicles can be recognized if pins 6 and 14 are occupied at the OBD diagnostic port.
It does not matter if the engine is diesel, gas, natural gas or LPG.

Some engine control units do not support the deletion of fault codes while driving.
For these vehicles, the OBD killer is then not suitable.

Which mistakes does the OBD Killer block?

The OBD killer is capable of learning can generally block all emission-related error codes.
During installation, the OBD killer learns the registered codes as expected errors. This process can be repeated as often as you like.
One of the most common mistakes is e.g. in connection with coked EGR valves code P0401. and the error code P0420 occurs very frequently e.g. aged catalysts.
It also deletes vendor-specific codes that do not conform to the OBD standard.
As soon as there is an error message that has not been "Taught/Programmed", the OBD killer will not intervene.
Thus, the full functionality of fault memory and engine indicator light is retained for all other error messages.

Where is the OBD Killer used?

The OBD killer is ideal for all sporadically occurring, exhaust-related errors such. P0400, P0401, P0402, P0403, P0404, P0405, P0406, P0407, P0408 (exhaust gas recirculation): After a repair of the exhaust gas recirculation, sporadic error messages often occur which often cannot be adequately clarified. The OBD killer is here a cheap alternative to the multiple replacement of all components.
Otherwise the error class of the catalyst (P0420, P0421, P0422, P0423, P0424, P0430, P0431, P0432, P0433, P0434).
Often the engine control unit repeatedly reports a faulty catalytic converter, although it is still in order.
This comes, for example, when using sports catalysts.
For performance increases or unexplained turbocharger problems often occurs the error code P0234: Boost pressure limit exceeded.

What do I do when changing vehicles?

When changing the vehicle, you can continue to use the OBD killer for all vehicles from the year 2008 onwards.
If the OBD killer detects a new chassis number after installation, all learned values will be reset.
The OBD killer then acts as brand new.

Will repairs become superfluous?

No.
If a repair has already been carried out for a fault, but then returns prematurely or reoccurs too frequently or cannot be solved or if no fault was found during diagnostics.
Instead of replacing all the parts again, the OBD killer is the better solution for the wallet and protects the environmental resources.

NB. OBD Killer is not able to display Fault codes and is purely "Taught" which codes to block by plugging the unit into the diagnostic socket, unplugging then plugging back in again. At this point whatever fault code was logged will be blocked or deleted by the OBD Killer. A generic Code reader capable of displaying engine fault codes would be needed when "Teaching" the OBD Killer to check which codes you are teaching it to block/delete.
Only "Teach" codes you know will not harm your vehicle.

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
• 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.

PURCHASE DISCLAIMER: Fabspeed Motorsport does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b).

Fabspeed Universal 90 Degree O2 spacers with catalytic converters

fabspeed

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
