header installation help

hi guys,

I got a good deal on a set of schoenfeld headers pt #116 for my 1971 nova ss 350. right now there is a very nice dual exhaust system on the car that the previous owner installed, but the car still has the stock manifolds on it. so my question is, the exhaust pipe is 2 1/4" diameter, and my header collector is 3 1/2" diameter. now also I would like to install a plain old exhaust cutout too. so, what would be the best way to go about installing the headers with the 3 1/2" dia. collector to the 2 1/4 exhaust pipe with the cutout? and what size cutout do I need?
