Debaffling a 316

[Scampi]

I read a lot of posts about debaffling, and figured I'd do this on my car.

My car is a '94 316 coupè.

I just read an article about two guys trying to debaffle, but ran into some trouble with some sensors.
On my car I could'nt find any such sensors, are they supposed to be there...?

My car was bought in Germany, and brought home to Norway.
The engine looks like it's brand new, and the car itself is in very good shape.

I just debaffled, but could'nt find any sensors.
Although it's idling pretty high, @ 1.5 - 2K... :/

But bottom point, is the lack of sensors on my car normal?
