^ I'm pretty sure I've thought about it every way to Sunday
The bend into
the turbine would be nice to get rid of, but physically the turbocharger just won't fit between engine and front cross member. Remember, this is supposed to be a 'bolt-in' kit. In the beginning I spent a lot of time thinking about going straight out the front like you're talking about. I even went so far as some sketches with a split radiator, but ditched the idea because it got considerably more expensive.
I didn't like how it would add feet to the exhaust (adding exhaust length adds backpressure).
The bend going into the turbine doesn't bother me. It's a 3" bend for ample flow and has some straight before the compressor inlet so turbulence shouldn't be too bad.
