SPITFIRE HEADERS Not angry....just dissapointed...

I recently purchased a pair of Spits from Harold, but haven't had an opportunity to install 'em yet...... So I hate to sound entirely stupid - but the Spits don't have flanges on the down end. How does an exhaust pipe connect to the unflanged end?

I plan to install the headers myself, then take the car to an exhaust guy to connect 'em to my tailpipes.
