Me and a friend of mine are swapping exhaust manifolds, and before we do it I would like to know if anyone has done this or has seen it done. He has a b16 swap, so the only thing I guess Im curious about is the length of the header. Maybe Im just worrying over nothing, but I would like to be sure that it will work before we begin the swap. I have a 00 si btw. Thanks guys.

 

You will be fine. B16 to B16. Assuming he didnt alter his exhast to fit one from an Integra. Just eyeball it. Theres a couple inch difference so you will know right away.

 

It will fit. just eyeball it you'll see if there will be a big differents but.. dont worry about it.
