Changing from PSE to normal Mufflers

[KoljaRenn]

HI all,

 

My first post here , beeing hiden reader for long time .. :)

 

Im about to change my original PSE on 996 2003 Carrera  to non PSE mufflers.

Several reasons , first , original ones are done , open on the bottom edges ,

cost of new ones in Germany are "insane" and noise PSE is making ..

 

So bought EISENMANN Sport Mufflers without valves ,

 

Now , questioon is not about how to remove mufflers , lots of articles around , good ones for sure but i could not find article

explaining what you should do with original wiring and vacum lines if you instal normal mufflers withut vacum valve ...

 

Im bit worried with electric part , do I need to change relay , reprogram DME ,

Also what to do with vacum lines.

 

On the other hand, would like to keep original setup of wires and lines, for the future potentialy, kids are growing fast .

So preffered option is minimal whats needed ..

 

I Have parts manual for EU cars also WManual for cars till 2001 I think, but could not find

any detail related to PSE vacum and wiring .. maybe searching wrong page .. :(

 

Thank`s for support ..

The PSE contol system uses a dash switch to manually operate the system as well as a speed sensors to close it under certain conditions.  That said, the control valves are vacuum operated, so if you disconnect the vacuum lines at the exhaust and plug them, nothing else is required to use the non PSE mufflers.  No reprogramming is required.

Yes, most people use a cut down screw or small bolt to block the vacuum lines at the valves on the exhaust.  Vacuum is used to operate the PSE contol valves, so if you remove the exhaust and replace it with a non PSE system, simply plugging the vacuum lines will result in the car not knowing that the system is not there and will operate normally.  If the lines were not plugged, you would have an intake vacuum leak which would cause problems and force the car to start throwing trouble codes due to intake mixture lean conditions due to the vacuum leak.  Plug the lines and you will be fine, it is that simple.
