No idea how they are attached, but will ask for you..... Lovely set up though right, I love the fact they've used all four studs on the flanges, must be a pig to get on and off.....
My only disagreement with it is the waste gate exiting into the muffler, I would have had them straight out and loud..... It sounds great anyway!
