Default Vetterman gains?

I've got an O-320, fixed pitch with exhaust of an unknown make. Don't think it's a Vetterman. Considering upgrading for a little more performance.

Anyone have any numbers on the Vetterman exhaust?

Vetterman has some numbers on his website, also an approach to a cowl mod which gave him a few more knots.

I spoke to Clint about this and other topics (intake type - e.g. cold air sump) and they had done some testing with interesting results. In summary, I recall that it is a combination of intake and exhaust that gets you the increase in power.
