How big of mufflers
What size muffler will fit under a '62 GP. I was thinking about Dynamax Super Turbos, but I don't know if they will fit. I believe they are 20" long. Or possibly Goerlich Xlerators which are 18" long. There looks to be enough room for either, but I want to be sure before I buy. Thanks.

I have the 20" Dynomax Super Turbo's under my GTO. You should be able to fit 12 of them under a GP.

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.
