Do i need a "swap" exhaust or will everything line up with a b18 header and a regular eg exhaust? Thanks

 

you might have to have the exhaust modified a little to line up. I'd say keep your exhaust for now. Do the swap, and if things don't line up, drive to an exhaust shop and have them cut/bend/whatever needs to be done. It shouldn't cost much.

 

Thanks man. I was thinking that but i like to do my homework.
