more flow from 10vt exhaust manifold

[Dave Aukerman]

In the coming weeks I need to replace my cracked manifold (89 200tqw).  The
replacedment is sitting on the garage floor and I was wondering if anyone
has had luck in getting more flow from the one-piece units on the cheap.  I
know all too well that the 2-piece is the way to go, but I don't have the
grand or more that it cost to get in the show.

Thanks,
Dave
