This isn't the OEM quad exhaust, it's the Velocity AP one - but the layout is similar to the OEM version (couldn't find a photo of the OEM quad pipe setup, apologies).
The exhaust tips (unusually for a modern car) also stay a uniform diameter from the back box, so what you see is what you get (though some say they're too small). The majority of car makers these days put large exhaust tips on their cars just for show, because the actual pipe diameters are somewhat smaller. The truth is that bigger isn't always better for flow or sound, but in such image conscious times as these, cars are judged on the superficial visible girth of their exhausts...
The Velocity (DAE in the UK) tail pipes increase the diameter slightly:
Interesting. So you adjust the Velocity system by sliding the joints with the clamps on in and out for left and right adjustment and rotate them about the centreline for height, then clamp it all up tight.The exhaust tips (unusually for a modern car) also stay a uniform diameter from the back box, so what you see is what you get (though some say they're too small).

If the Aston quad pipe system is consistent with the tailpipe practice on the V8V, V12V DB9, DB11, etc then I'd expect the joint where the Velocity system is a simple sleeve and clamp to be a ball joint, so you adjust each pipe up and down and left and right by slackening the clamp, rotating the ball then clamping back up. Either way it should be possible to align all four pipes.
