Do AFR 225s require a special header??

[slvr302]

Do AFR 225 mount up to standard headers without any adapter?

standard headers should work.........although, i believe i would step up my header size from 1 5/8" to 1 3/4" ...........later, hotwheels

header flange is stock, but raised about .250", as long as you have clearance under you floor you will be fine, btw I would recommend a 1 7/8 up to a 2", that has a HUGE port, I would consider 1 3/4" the bare minimum, jmho
