jdm headers and downpipes are not interchangeable with usdm headers and downpipes...cuz i tried putting on a usdm gsr downpipe on my jdm b16 upper half...and the bolt pattern is different...but most b series headers should fit cuz i got a usdm header on my jdm b16 motor...and it bolts up fine...just that i have to fabricate a test pipe to connect to my catalytic converter....on my ef hatch....
