Quick question guys, do all 5th gen (94-97) Accords use the same header, or 94-95 are different from 96-97?

 

They are the same through the years. However, Vtec headers are different from non-Vtec headers (ports are different).

 

SE,LX uses 4-1
EX uses 4-2-1 header

 

like he said, VTEC has a 4-2-1, the rest have the 4-1.

 

it's actually the pattern of the exhaust ports on the head that is the problem. on the VTEC, the #2 and #3 cylinders are closer together. whereas the non-VTEC has all 4 spaced equally. (or do i have that backwards guys?)

The port patterns are the exact same. The only difference is the vtec manifold is a 4-2-1 design with the o2 sensor on the secondary pipe. The non-vtec manifold is a 4-1 design with the o2 sensor on the primary section.

 

ah, okay. my bad. then why are there always 2 different part numbers for the EX vs. the LX/SE?

and is it the same header for the 90-97 since it's still the F22 block, just in different variations?

 

there is always 2 different part #'s because of the o2 sensor location.

and i belive the 4th and 5th gen exhaust ports were different.

 

correction i have an lx and i used a 4-2-1 dc header
so i dont think thats accurate no offense no harm intended just my two cents

 

we assuming the accord is stock
of course u can change your header from 4-1 to 4-2-1

 

same goes for stock he he it was 4-2-1 ill give it up at that
