all b-series headers fit up to any other b-series heads. it's the length of the pipe down by the cat that changes. so you might have to extend/shorten depending on the car and engine. I'm not certain what you'd need to do for your specific situation.

 

The B16A block is shorter than the B18C block. The header may not clear the oil pan. Has anyone actually tried this?

If the header is for the B16B (CTR), it will fit fine with an appropriate catalytic converter.

 

Bump for someone who is certain!

EDIT: This is for a 1998 Civic Ex coupe. I know the 96-00 EX headers are the same and the ex/si exhausts are the same. So could I use B16 header to fit and reach my stock Civic cat?
