Sport Exhaust on 2005 987

[berty987]

Update :

System now installed and a manual change over switch placed in the circuit to allow driver control of the system. Interestingly the PSE exhaust is actually quieter than the standard exhaust when in quiet mode. I like the sound of the exhuast when switched to loud mode and the flexibility to revert back to quiet when conditions require. Definitely an addition worth doing if you require a more sporty sound but not sure if you can live with a loud exhaust on a daily basis. It will also pass any emission controls without issue , so added peace of mind.

Installation now complete and fully functional. The PSE silencers (mufflers) are a direct fittment onto the 987S manifolds. The vacuum tubing and control valves have been retro fitted , all parts obtained from my local porsche agent as spare parts. The only difficult parts to obtain were the plug for the solenoid valve and the connection pin for the plug on the rear DME. These must be sourced from a VW dealership as spare parts.

Just to recap , this is a fully operational PSE fitted to a MY2005 987S. The vehicle did not have the PSE control wiring originally installed , this has all been retrofitted by myself. There is a TSB on this forum that will give more details for the wiring of the control switch , the switch panel with PSE button can be bought as a spare part , then its just a case of wiring back to the rear DME as described. The PSE solenoid is activated by pin C14 on MY2005 cars, the other side of the solenoid is connected to a Red/Blue wire on Pin A8 which is permanently live.

The PSE is controlled by the SPORT button from the front switch panel ( my car has sport chrono) but unlike the later 2007 models , the PSE remains active regardless of road speed. To get the PSE operational it must be enabled via the PWIS unit in the gateway module. I have also installed a manual override switch to allow the PSE to be activated regardles of the sport button , so the PSE can be switched to being permanently active. :clapping:

For anyone considering buying a sports exhaust for the added sound, I can reccommend this item. Not only do you get the benefits of the sportier tone , but you also have the ability to revert back to a quiet mode for motorway journies , or when at trackdays all at the touch of a button. Ok... there is no performance gain, but the system is emissions compliant and a great enhancement to the car. From what ive experienced so far , retro fitting the PSE to a MY 2005 car actually results in a better system than that of the Rs60 as the exhaust has no added software controlling its operation below 40 mph.

A few words of thanks to : Porsche librarian, Loren, Wizard, and Richard Hamilton for all their help and support.
