I have a JDM OBD1 GSR and I'm swapping it into my 95 Si/Ex

I can't seem to find the answer to this anywhere but everyone tells me that the exhaust will not fit.
What parts do I need and what kind of fab work will need to be done to hook up the exhaust?
I don't want to spend too much money on this since I am going turbo in 6 months, but I need to pass my emissions once the motor is swapped.

 

If I remember correctly the GS-R downpipe is longer than the civic unit and will require you to shorten the intermediate pipe.
