i have the megan d/p with flex piece... the ground clearance sucks balls... i eventually removed the flex piece (because there was a big asss hole in it) and got my downpipe modified to sit closer to the chassis (the welder chopped off about almost 2 inches from the down part of the down pipe.
as far as manifold cracking... just don't heat wrap it and you should be ok. heat wrapping manifolds are the #1 reason why they crack.
