I need to know a quick answer because someone i know wants to sell me his header. Will a 92-95 si hatch header fit into a all stock, including all AC components 88-91 crx si. I know about the O2 sensor being in a different location, I can change that but how about physically fitting. thanks all

 

yes

 

yup.

 

thanks guys

 

Is it a 4-1 header or a 4-2-1? 4-1 No, 4-2-1 Yes

 

D-Series will fit D-Series as far as the head is concerned.
