Ok so I am kinda new to this forum and i am looking for a header for my b16a sir 2 engine in my 1994 honda civic dx. I was wondering what header would fit my engine. Does any b-series header fit any b-series engine? or what is the rule that people go by? Sorry if this is a repeat post but if this has already been talked about please direct me towards the thread. Thanks

 

any b series header will fit any b series head, but they might be different lengths. gsr headers are longer than an ls. if you want one for that motor buy one for a 99-00 si civic and it will fit perfect.
