2856361 ‘68 383 & 440 single exhaust resonator detail.

Did 67-68 Imperials have resonators with the optional 360hp 440?

In ‘68 manual imps used the same as the Chrysler without HP which is different than the Dodge.
Plymouth does not show one

HWYCRZR, FYI, I have an NOS in the box zinc coated #2660525 muffler for a single exhaust for your car. LMK if you are interested in it.

 

[HWYCRZR]

I am interested if I can afford it.

I will PM you

Thanks

My 68 440 Dual has no resonators...from the rustiness of all the pipes, I think it's original still.

The 360 hp 440 Dual option was only in 68. The only year you could get a factory HP option for the Imperial...at least according to the brochures.

Thanks to @68plymouth383 I received an original exhaust hanger. It cleaned up nicely. Soaked it in my solvent tank for a few days which loosened up the old undercoating an actually softened the rubber. Sand blasted it, acid etched it to give it a little bit of a zinc phosphate coating and then tin zinc coated it.
Some day when I find the right rivets. I will replace the rubber.

From this.

To this.

Would you care to share what you disagree with from this post?

Thanks

Let me see what 68plymouth383 has. He says he might have a good used original hanger.
For the NORS hangers you found I am pretty sure I would have to turn the bottom of that hanger around for it to fit right. There is only 4-1/2” of pipe that the hanger can go on. I hate to spend that kind of money and still have to rebuild it. But if I find that is my only choice... I will do what I can. I will need a 2” clamp for sure though.

Sorry, i just have to big fingers to use my smartphone correctly, nothing to disagree with your post

 

[HWYCRZR]

Not to worry the fast scroll gets me as well. I just asked in case you had some different information. I try to suck up all points of view and knowledge tidbits.

I just picked up two NOS pipes with resonators. My plan is to use just the resonator and turndown on my duals. They are both right side pipes but if I cut them at the resonator- voila! duals with the correct turndowns!
I am doing this to replace the chrome tips I have on the car now. I wanted to go back to turndowns and at $40 a piece i couldn't go wrong.

If your looking for new rear hangers that are near identical to the originals. Hwycrzr started a wanted ad that i had added some pictures. Its about 6 pages into the wanted section. The title is Tailpipe support single exhaust 66-68. Dual hangers are available...

 

[hemidart1]

who makes the dual hangers?

 

[Dodgedon]

I would post a link if i knew how. There is a 2 page discussion about these hangers in the wanted section. If you are interested i can try to get a better deal on a pair. Thought i may try selling these on ebay.... surely some one would find these helpful/useful.

 

[hemidart1]

I sent the pics to the guy who sold me the pipes- he has a warehouse full of old stuff and he is looking for the hangers

 

[Dodgedon]

Thats funny, my guy has a building full too. Why these guys don't organize the parts and sell on a open market i dont understand....
I think there can be a fear that if people found out what they have it could start to disappear. I always try to protect their identity on the internet for that reason.

Here is the link to what Don was talking about.

 

[hemidart1]

I gave them a quick coat of engine aluminum paint and engine clear coat.
Not bad for $60 for the pair
