1996 s14 KA Header/Cat questions

[conkerbfd11]

So I have a nearly bone stock '96 S14 KA, I'm thinking about dropping some money into a header, sounding like i'm leaning towards a 4-2-1, for more low-end, but I'm wondering if there is such thing as a header that can just bolt on in replacement of the stock manifold, or bolt directly to the stock cat, I don't want it to interfere with me passing emissions, and I'm not really in a spot to buy a new Catback system and what not, so If you know of a good header that will bolt onto the stock cat that bolts on and fits decently please let me know, it'd be much appreciated.

I thought headers went down to the cat. If it's got O2 bungs it should cat compatible.

If you're not planning on supercharging or building an N/A motor, I wouldn't bother with a header.

I have a DC Sport on my S13 KA, must be a 1WHP gain.
