. . .

Most production exhaust systems will maintain around 2 lbs to 3 lbs of pressure on acceleration.
A ha! That's why I get blue balls while trying to accelerate in a production car.

This has been instructive. Is there a way to measure back pressure for the common man or is that only a big fancy OEM task?

With a ported TB, LS6 intake moderate cam, high flowing heads, and stock manifolds and cats, I must have quite a bit of BP.
