I say the cat...

I don't know.  There'll come a point when you're flowing enough air
that it'll be slower than a .63 turbo, because it'll create more
backpressure before the turbo.  I'd stick with the stock early one,
...as a matter of fact, I have ;-).  I'm coming from a drag racing
perspective, though.  For all around street performance, I bet going
to the late model turbo would be worth it.

Compared to your stock exhaust, I'd bet money it will.

You must have pretty good traction.  I had to get up into the 92s
before I could break into the 14s.  What was your 60' time on that
