does anyone know if the jdm type r header flange that bolts to the exhaust the same as a usdm type r header. i'm about to buy a test pipe that came off a usdm type r but i wasnt sure if the exhaust flanges are the same. thanks

 

the flange does not point the same way and I believe the JDM one has a 2.5 inch flange vs a 2.25 on the USDM R
