Which is completely inapplicable for anything except the "standard" types of engines.
Lean Burn is a slightly different beast, however, the converters were placed in front of the engine on more than just the lean burn Civics. The setup can also be found on CRX HF, Civic STD hatchback (with D15B1 engine, not B2) and CX/VX models, possibly others, those are only the D-series variants.
The STD hatchback model was equipped with a D15B1 engine, which was exactly the same as the D15B2, but with a mild(er) cam. In fact, you can get 20 HP just by swapping the cam and using the OE ECU for either engine, if you had that one.
Regardless, I don't think the VX will like the cat being further away specifically for the lean burn issue and keeping the cat warm. You'll be a gross polluter even when fully warmed up because of your NOx emissions, which won't be converted properly.
That notwithstanding, the information is there, and readily available to make the header fit your car.
