Hey guys,
does anybody know if an oem usdm integra type r b pipe would fit onto a 00 civic si?

I just wanted to see if anybody has done it so I would know what type of modifications I might need to make to make it fit.

If anyone knows I'd greatly appreciate the help!

 

i know the pipe will fit a DC header with a little massaging of the bolt holes but i'm not sure about the factory bolt pattern

 

i used a 94 gsr b pipe on my 96 ek sedan..
i had to extend it slightly.. i removed the cat tho..
i would have had to shorten it if i used the cat..
