I'm thinking about buying some DC 4-2-1 ceramic headers off of some forums similar to this one off a '96 H22a. I have a '01 H22a and the guy said that the header itself will fit but the downpipe/flexpipe is a different length. Is the 4th gen distance from the header to the cat longer or shorter than the 5th? Does anyone happen to know if DC sells the downpipe/flexpipe separately? Price? I'm just wondering what my options are here. Thanks in advance.

I know that the header will work because when a buddy of mine swapped an H22 into his 92 Si, he used a 5th gen header.

 

I'm pretty sure the greddy is longer because its only made for the H23 but must be modified to fit an H22. I've heard you have to move the cat back further or take it out completely. I am planning on getting the greddy header on my 5th gen and getting a carsound cat and moving it back.

If anyone has pics of a greddy header on a 5th gen(especially underneath) I would love to see them.

 

this has been covered, one of them is longer than the other, can't remember which though, i think the 4th gen header is longer than the 5th gen. try using the search function next time if you would please
