06 Cayenne Turbo S Exhaust

[madburg]

Hey Loren,

Would you be able to look up the diameter (spec) of the stock down pipe on the '06 CTTS (2.75"?)

Also would you have a diagram of the exhaust system end to end (I would like to see how many individual pieces and gaskets, etc...) on this model.

Sorry, Porsche does not publish diameter of exhaust parts so I would have to measure just like you.

:) Will do, thanks.

Interesting, is that 4 Oxygen sensors on the downpipe; am I reading/seeing this correctly?

[Loren]

In the US/Canada it is one before each cat and one after each cat.

Very Interesting, never knew cars had 4 oxygen sensors. Loren, question is the part number #9 & #10 (down pipes of the turbo's - 1st Cats) different for the regular 06 CTT versus the 06 CTTS or are they the same. If they are different then I would have to guess they are larger diameter on the CTTS, otherwise the same.

[Loren]

They appear to be the same part numbers.
