Meir..
I'm in Australia - we have ROW specs where only one set of cats and O2 sensors are fitted, both mounted in the pipes just prior to the muffler. The exhaust manifold is just that - a manifold without cats / O2 sensors similar to US 1997-99 2,5 models .....

Che's cat delete pipes for 1999 - 2004 S models don't come with O2 bungs in the pipes for me to fit the sensors, so I have to weld them in.
Perhaps I should have purschased the Che's 2.5 pipes which have to bungs already installed......
