MMK - you have the cool manifold that the catalytic convertor connects directly to, in front of the engine.

1 - Any Civic CX
2 - Any Civic VX
3 - 4th gen Civic STD
4 - 2nd gen CR-X HF.

The only thing is that you must use the same catalytic convertor as the manifold you have - the bolt patterns are different, except maybe the CX/VX ones.

In theory, depending on your emissions laws, you could get any D-series header and cat combo, and you'd just have to slightly modify your exhaust to fit it in there... the B-pipe would have to be cut and welded to length.

Most of the images for headers on RockAuto.com show the basic header from the 4th gen Si Models... they're all nearly identical, from 88-00, so they're basically interchangeable. The one that you need is the one that has the cat sitting directly in front of the engine, which is CX/VX and HF/STD models. Some DX models apparently also had it. Year is not a concern, as long as the engine is 1.5 liters or has a engine code beginning with "D" (D16Y7, D16Y8, D15B2, D15B8, etc.)
