The X and Ultraflows I have on my 78 TA and the Camaro/IA are pretty quiet.
The 3" on my TA ran the same with the 3" mandrel tailpipes as the car did open headers-with the weight of the system added! The IA has a 3.5" X and narrows to 3" Ultraflows and tailpipes.

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.
