I just got these on line from ebay, where the seller claims they are for a H22 engine, and it came off of his 95 lude. After reciving it and comparing it to my stock 93 vtec header and downpipe this megan set is not only too short on the down pipe, missing a hole for the 02 sensor but also the tubing diameter is smaller.

does anyone have any idea what engine this megan header/downpipe goes to?

h23 maybe?

 

Look at the flange on the header where it bolts to the head and see if the ports and bolt holes line up with your H22 header. The H23 has different ports than the H22.

 

I dont think its for a 4th gen. they have longer piping after the flex pipe. maybe an sh or base 5th?
