Just wondering if anyone know how different the patterns are.. I know the outer to most bolt holes are different but what about the spacing on the rest of them? The reason I ask is I stumpled across this header and for the price you cannot beat it.
obx manifolds are known to be pieces of trash. bolt patteren is off and so is port spacing. ive seen honda guys use stock dsm manifolds and they really do look hacked.
could you email me a DXF of the the dsm exhaust if you have it im wanting to make my own turbo header (torq 22 bridgeport a bit old school but does the job) thank cobeykrell@yahoo.com
