I have run multiple 2.5" systems at 425-450HP at the wheels. Engine dyno 2.5" at the 540-560hp range. Flowmasters in most cases. I like the Flowmaster crossflow system. Sound is very unique for a Flowmaster. I would do 2.5" sys. with cutouts. Never put smaller tailpipes on a system.

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.
