This setup uses the stock 964 headers. The turbo mounts where the cat converter usually goes. Here's a better pic:
The cat was moved to the back in place of the primary muffler. The secondary muffler was retained. The blower fan was removed and replaced with the factory "cup bypass." The airbox is deleted and replaced by a K&N filter that mounts directly to the hot film air meter--wasn't mounted when I took the picture--which feeds the turbo through the big black tube.
This setup is much like the Ruf 964 turbos except they retain the blower motor and the stock airbox.
