It's to big and has a single outlet. I have the Grp A header and it is 2 pieces and has duel outlets.
This looks like of one the Grp N 2.5l ones. It's going to be a REAL tight fit on a street car.

Actually, most of the Gr A cars that I have seen pictures of did use 4-into-1 headers like the one that Markus is selling.

Some info. on header part numbers can be found here:

There were two types of Gr A headers that are seen on the parts CD. One is what everyone calls the "Rally Header". The other is the Evo III header.

The Gr A catalogue lists additional headers for the various years of Gr A competition. One has to keep in mind that some of these headers were designed for 2.3L engines while others were designed for 2.5L engines. All of these headers will require a custom exhaust and will have a single outlet.
