Although it is a four into one configuration, that unit is to fit Jap spec 91-94 NA that would indicate

Something to check on when going for aftermarket headers:
Depending on the brand, you may loose your top heat shield that means the engine bay will run hotter, including the intake manifold. Ceramic coating can fix that, but can be expensive.
Also some may not have any bracket stays at the secondary pipe/s join to relieve the strain on the head mounting studs.
