ok,im posting this for a friend..hes putting together a D series turbo kit on his EH hatch. He has a 5 bolt pattern setup on the turbo side,and i found a 5 bolt downpipe. But the guy said it came off his GSR integra B series turbo setup. I figure since its still the 5 bolt pattern,it will work. But are the way Downpipes ran on b and d series setups completely different?? i dont want my friend to buy it,and not be able to use it. any help will be appreciated.
