Ok fellas, need a lil help; can't find a concrete answer.

I'm looking for a spare stock exhaust manifold for my '89 Si. I know the HF manifold is different(I have one in case anybody is looking to do a turbo project), and the DX manifold visually appears to be the same as an Si. I can't find one directly off and Si, but if the DX manifold is the same exact part I'll grab one of those. Can anyone confirm this fitment?

Thanks

 

DX, LX, EX and Si are all the same

 

jijcrx is right. The only uninterchangeable models is the HF. Everything else is jive
