I have a 94 Accord EX and i have some extra headers that are for a DX. They are DC-Sports Ceramic Coated 4-2-1, 2 peice headers and I understand that DC makes that header for the LX/DX/SE and a differernt model for the EX. Does anyone know why two different models are made(what the differences are)? I am trying to put the DX header I have on my EX car, just at a glance they look identical, Is it an easy modification?

 

well the stock DX headers are thin as hell. The EX are thicker. So I would assume the aftermarket EX headers are thicker than the DX aftermarket headers.

 

well i would assume the headers are made according to engine specs, taking headers from a different trim although, may look identical, might cause damage by you switching them

 

A '94 EX F22 engine is VTEC, and a DX/LX/SE F22 is not. Otherwise, I don't know.

 

All blocks are the same

 

NOT the same... the VTEC motor has the exhaust ports spaced differenty, non-VTEC motors have all the ports evenly spaced.
