Are all B series headers the same size???...got this kid wanting to sell me his header and right now he has it on a gs Integra..I want to put it on a 98 GSR B18c1...Will it fit????

 

the b16 ones are shorter so you cant use those on a b18 but you can use a b18 on a b16 it will just sit low. all b18 headers are the same heights the only differance between ls and gsr is the gsr pipe is shorter in the back so the ls one will be too long but you just have to cut yer exhaust (or the downpipe) and re-weld the flange, then it will bolt up.

does this answer yer question?
