In Pursuit of that Mythical Commando 273 Sound

In 1965, Chrysler introduced the Commando 273, as a high performance version of the 273 LA engine. As part of the high performance package, a somewhat unique exhaust was installed. The Commando 273's had a noteworthy exhaust sound, often talked about, but rarely recorded. I have a '67 Plymouth Barracuda, originally equipped with a Commando 273 engine. The original exhaust was long gone when I got the car. And, years ago I swapped in a '68 340 to have with the 4-speed. More recently, I decided to partially return the car to have a semi-original exhaust system, in pursuit of that original sound. This is the video of the exhaust work, and sound so far.
