The best exhaust manifold for these I4 conversions is the unit from the Audi
80. In its 49 state version it is a 4 to 2 manifold pointed down, towards the
driver and to the front. The CA version is a single but large port (4 to 1).
These are found on the 1988 to 92 4 cylinder (3A engine) cars in the US and
the Audi 90 in Canada. The rear exhaust flange is unusual, so get it at the
same time from a junker. AFAIK, this is the same manifold as used in the
TIICO.

As for the routing, the mount points and the use of flex, see the archives!!!@
