Another post mentioned Precision Exhuast, took a look on thier site.

Been considering dual exhaust on the C code, swapping a 4 bbl 4100 and matching intake I have onto the engine when I pull it for clean-up and painting.

The Precision site lists one dual exhaust system for 289, 302, 390, and 428 for '67-'69. As I have a spare 390 dual exhaust setup for my S codes, which I assumed would not fit, it now appears all I need is the correct H pipe?

Or would this swap require different exhaust manifolds as well? Don't seem to have a reference that lists those part numbers to see...

The "H" pipe is what is different on their systems. Precision Exhaust uses the same mufflers and pipe diameter throught the systems.

They offer an "H" pipe for the 289 HiPo exhaust manifolds too. We have convinced them to make an "H" pipe that allows the use of 351W manifolds on the 289/302 engine. 351W cast iron exhaust manifolds, the poor mans HiPo manifolds.
