That is some of our data as well Mike.
 . Substitute Magnaflow for the Straightline Performance data. This is data that shipped with the CDs.The early Spin Techs were pretty loud.

Tom, any plans for updated testing? Many new options since the "Silent Power" production, yet very little accurate/reliable testing data out there since then. The testing you and your father have performed over the years is VERY highly regarded and appreciated by many of us.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
