Exhaust Pros/Cons for Slant 6

Hi all ... My '68 Barracuda project is moving along and will start with a rebuilt '74 /6 comprising of a factory bore, mild cam upgrade, standard intake manifold with 2bbl carb and dual exhaust header) + A908 drive line. I was intending to build the exhaust system with the '74 motor as a dual exhaust, given it came with aftermarket exhaust headers.

I've watched several Uncle Tony's Garage YouTube videos breaking down the /6 engine. One of the things he advocates against is dual exhaust. In this video (start at the 28:32min point), he promotes a single 2.75-3.0" exhaust to avoid heat-velocity-backpressure performance and sound issues.



If anyone has thoughts/experiences on this please opine !!!

@RustyRatRod I believe I ran across a video you posted in this Forum in response to people shaming the sound of a /6, but yours sounded great. I am interested in your experience and advice on the topic, and if you've experienced any of the sound characteristics he mentions with your build?

Eventually, I want to acquire a '81-'87 /6 and build a more performant engine. But for the short term, I want to push that engine build spend out to another year or more, and simply get the car on the road this coming spring/summer.
