911s. Never had any obd ...... Just sayin
And no those dont meet up.with exhaust. They blow over the exhaust pipe in a heat exchanger picking up heat and blows into the cabin
For turbo questions you would be better consulting the 930 forum or the gt2 forum

I think we have some confusion.

What is the purpose of the pipes in the following two pictures.

Then the air goes around the headers on its way to the cabin.



That's not a stock muffler, but you can see the 993 exchangers.

Only one person is confused. No merging. A heat exchange takes place with the air being blown from by the fan picking up heat from outside of the headers, and pushing on into the cabin.

What are the ports in the back for?

Actually no...it is well know that the 95 is much more prone to stalling than than a 96-98 when a LWF is installed.

The ports in the back connect to a flexible tube which then connects to the heater box. The heater box (there is one "box" per side) is a device which, depending on the heat setting inside the car which the occupants select, will either allow the heated air to move forward into the cabin to heat passengers/defrost the windscreen or allow the heat to dump out near the rear wheels and not move any further forward in the heating system.

I get it now. I feel stupid now for not seeing it right away. The exhaust manifold is inside the heat exchanger. I was looking at it as an exhaust manifold with four outlets.
