Yes, and of course the HP manifolds got the duals, that is a given. It's the low po engines that are curious, like a T code 440
To my knowledge the only exception to this is the 1970 Sport Fury GT which came standard with the T code engine and factory dual exhaust.
He actually discussed that with me. After I placed my order I was called and asked about what muffler style I had. He said some used a longer muffler. He also said that sometimes due to variances like that he left the pipes a little long so that there were no issues on the longer cars. Better to trim than have to add.One word of caution about Accurate.
When I ordered duals for my 66 Fury BB, the exhaust pipes were exact two inches too long, the exact same difference in the wheelbases between the shorter Fury and the longer Dodge and Chrysler.
I would still use them again over TTI though.
I think most 70 C body T code applications were dual exhaust weren't they?
Interesting that the engine image shows an air cleaner that Mopar never built, to my knowledge with the rectangular inlets.

Much of Mopar literature has incorrectness in it which suggests it was written or drawn before production.....
Every one I've ever seen, was
This post has had me thinking and in my research I discovered some information I wasn't aware of. The same rule of thumb still applies about the exhaust manifolds but it is interesting that the standard "T" code 350 hp was the only 440 offered on many models and was only available with dual exhausts and dual snorkel air cleaner. So when you say that "Every one that I've seen was" you are correct when it comes to certain years and models. I have compiled a list of what I have found going through parts books, service manuals, brochures, pictures etc.... I knew about the Chrysler's, the wagons and the 70 Fury GT but much of it I was unaware of.
1969
The 350 hp “K” code engine was only available in the Chrysler line with a single exhaust with the exception of the Town & Country.
This same “K” code engine was available as an option in the Monaco and Polara and Town & Country’s but it came equipped with dual exhaust in those models.
The 375 hp “L” code engine was an available option in all Monaco’s, Polara’s, Fury’s and Chrysler Models with the exception of wagons.
1970
All Chrysler models with the standard 350 hp “T” code engine came with single exhaust with the exception of Town & Country, that would come equipped with dual exhaust. All Chrysler models, with the exception of the Town & Country were available with the 375 hp "U" code engines.
No Fury's or Polara’s, were available with the 375 hp "U" code engines.
Fury’s and Polara’s with the optional “T” code engine were equipped with dual exhaust.
1971
All Chrysler models with the standard 335 hp “T” code engine came with single exhaust.
The Polara and Monaco models with the optional 335 hp “T” code engine came with single exhaust.
1972-1973

First, thank you for the leg work...
I have a T code 71 with factory dual exhaust,. So it was at the least, optional. I will add that any 71 polara with a 440 I have seen had dual exhaust. I've been looking for 35 years and have seen few 440 cars, but they had duals. Perhaps Steve or Carsten will chime in on that...
2nd... You sound like Jeff Godshall, please don't say the U code wasn't available in the 70/ 71 polara. They are out there be it under the hood of a police car or civilian car, some got out
Thank You Doug..... I would swear that all 440 1970 and 1971 Furys, Polaras and Monacos had dual exhaust. I made this argument many moons ago on this board. I was told it was optional by many....... so to keep the peace here I wrote the "at least optional" ..... Sometimes I just dont have it in me and I move on, I dont like my face blue
