Exhaust System
This is the dual exhaust, 400HO (with long branch manifold), convertible system of my car.

Pictures were taken at various times during restoration work.
The Pontiac parts book shows the front pipe(s) consisting of (2) and (3) pipes. My system has been replaced several times over the years and I don't recall any time that the front pipes are not single piece.
The convertible brace offers a challenge to route the system without interference and rattles.
Two resonators
The muffler has two pipes in and two out.

Axle looks better here, huh?
A rear hanger assembly is visible here behind the tire..
These hanger assemblies are the first thing to hold the system since the manifold.
Exact Detail actually captured the system pretty well with their 68 Convertible Model.  They just didn't capture the very heavy body color overspray that my car received from the factory.
