The Powerflow exhaust will not make a dramatic difference. I think maybe I
noticed a little more power and climb but definitely didn't blow my socks
off.

The lower drag of a new paint job (esp. if all control surfaces were
balanced and put into rig) can add a little bit of climb and speed

Does the plane have a 4 cyl EGT/CHT by any chance? Any info on
if the spread was about the same or any narrower, afterwards?
