I'm using the log type stock 72 455 exhaust manifolds. I'm still using the 2" exhaust system that supported the previous 350 engine. I'd like to use a factory HO style 2 1/4" pipe from the exhaust manifolds back to the chrome tailpipe splitters. Will the 2 1/4" exhaust pipe seal with the stock exhaust manifold? Can I hone out the outlet of the stock exhaust manifolds a little for less of a bottleneck?

paul,
What i did on my 72 was have the exhaust shop use a short piece of the smaller pipe and then flare it to fit the larger dia. pipes. this doesn't look stock but it does work.

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.
