I think the thing with forced induction builds is that an exhaust that's TOO free-flowing won't be able to make boost. I'm hoping the FI exhaust and HFCs are restrictive enough.

Well, build enough boost to stay in it's efficiency range. I'm worried about my midpipe being too restrictive. Instead of 3", it's 2.75". Keeping my eye on my top end results.
