[Exhaust routing HR34 vs ER34]

I have an HR34 sedan that was swapped to an RB25DET. I'm trying to track down some exhaust systems but none mention HR34 likely because it is a NA. 

If I buy an Er34 system will I have to get custom routing done or will it be the same as the HR? 

[Release Bearing Question]

Hello! 

 

I have a really strange one here. I purchased a 2001 R34 4 door that was swapped to a rb25det neo with an rb20 box one year ago from a reputable importer. The release bearing has been making noise since I bought it but parked her for the winter and thought I'll change it out next Summer. Fast forward to today, I've purchased a quality clutch Kit for a push type clutch since it makes sense based on the slave cylinder placement. However the current bearing that was on the car spins along the inside rim while the new one purchased with the clutch kit only spins on the side rim facing the pressure plate. Should I be ok re installing with this newer, larger bearing? Pictures attached. I've already pushed the sleeve onto the new one. 

 

Please help!
