I'm looking to put a set of 97-99 Taitec headers that use the ball style flange onto my 91. Unfortunately they do not include the adapter pipes to mate them up to my 91 cat flanges.

The Taitec headers use the same size ball connector as 97+ OEM headers, and the same gasket, so I believe that any adapter that works with OEM 97-99 headers will work with the Taitecs. What I am trying to determine is what adapter pipes are the same size and will connect properly to these headers... specifically wondering if the DC Sport header adapters will work.

I know SOS and Dali both sell adapter pipes... but does anyone know the ID or OD of the tubing used on the DC adapter pipes? Or the size of the collector tubing on the newer DC Sport headers?
