The 1972 Chrysler Thread

[73Coupe]

I would think that 1971-1973 exhaust design would all be the same, no? It's the same chassis. What would be different to the point of a 1971 specific dual pipes not fitting a 72 or 73?

Edit: the exhaust manifold outlets included in the above. I would just order a '71 dual set and tell them it's going in a '72.

I’ll have a look at the parts book. My worry is less the engine side than the attachment points or the rear length (as the cars had a facelift).

As well, my car is a T-code so what I need is a dual setup like there was on the T&C with regular RB engines.

@ayilar ... just my $0.02.

I am more where @73Coupe said.

i would be stunned if unibody/underside dimensions 71 vs 72 would be materially different. I have been, however, stunned before by hardly visible changes that required a part number change for to allow for fitment.

for exhausts, my only experience with this is the tailpipe clamp part number for my '71 Polara WSP vs. my '72 Fury NJ statie were said to be different. after both were professional done, i didnt see any physical difference between the two cars vs each other or before the replacement vs themselves.

sorry but i don't have any dual exhaust '71-'73 civi-car for fitment/attachment references tho.

all that said, and all stuff I am sure you will/did do and more to get this right: (1) somebody here knows this answer, and/or (2) if they don't weigh in bfore you have to make a purchase, then telling vendor what youre doing before you buy could be helpful to you.

@ayilar I have a pending order for a stock 1971 dual system from Waldrons....expected to arrive sometime in the next month.....so can provide any dimensions or photos of the parts if that would help. My car is a T-code.

The attachment points on the chassis are only (2) per side - above the axle at the cross member and just in front of the bumper at the unibody "frame rail" member.

They're about to start up the C body blink and you'll miss it production?

We get February for our run of product. They are nice people to deal with, though.

I'm an auto mechanic by trade and do custom bending, my Newport has a dual exhaust I built, 2.5" pipe was tight around the shifter linkage and torsion bar on the driver's side, lots of room otherwise

FWIW I have a NOS rear bumper for a 72 NY with rubber guard holes. Any 72 guys interested send me a PM

As we well know, there is something different about the later C-Bodies from 72 to 73. IE: the rear shocks are different, so we know something changed toward the rear of the car during that time. I would give Waldron a call and see what they have to say about the '72. Maybe they have a workaround.

Also, a shop near me does custom exhaust work. I know they could bend up a dual setup for you.

What you wrote about the rear shocks is exactly why I am not jumping to conclusions re: any equivalence between 1971 and 1972.*

--> My plan is to call up Waldron, sooner rather than later given their lead time. What I had been hoping, was that someone here has used them (or another company, such as TTI) in the past and could tell me exactly what they ordered, so that I could start from somewhere with Waldron. Not having heard from anyone (yet?), I'll jump in to be the proverbial test hamster and report my experience given that other/future 1972 owners may be interested in the answer.

*: All 1972-1973 Chrysler owners should be advised that the KYB KG5512 rear shocks that work like a charm on 1970-1971 Chryslers and Dodges are too short for the 1972-1973 Chryslers -- see here for more info. In contrast, the same front shocks work on 1970-1971-1972 P/D/C C-bodies.

Switching for a moment to documenting 1972 Chryslers that are still around, here is a beautiful HT8 NYB 2dr that @coco spotted for sale on FB in Ventura, CA. I was interested, either for another member or for myself (I know I know, I want to trim my fleet but I have the disease...), and had a long video call with the owner. I have decided to pass, and so has the other member.

CS23T2C126889 looks almost exactly like a movie car available for hire in New York, and for some reason the CA owner used the photos from that other car in his ad. Don't ask me why he used those other photos, he never answered that question.

What tipped me off was the different top once the video call got rolling, and the fact that the car for sale had the R48 power antenna (the movie car does not). that something was different is that the car for sale in CA but the vinyl top has been painted over (from V1T original to black) and there has been work done as replacement lower body moldings have been screwed on. The interior is in great original shape (a custom stereo has been installed, with huge speakers in the trunk, but the car has not been butchered in the process -- it all looks pretty good).

Here are some photos for records (the FB ad has been pulled); apologies for the poor quality, those are video screen shots.

There are some dimples (rust?) on the RHS C pillar under the black vinyl. Note that the original carb works and comes with the car, but the seller wanted an Edelbrock and has installed one. There is a new radio under the dash, the original is still there. The tan seat hinge covers are off on both sides but come with the car. The S61 tilt rim blow wheel has a crack and the horn does not work. The original wheels are gone and replaced by huge rims, the rear fender skirts have been removed (the seller has another '72 and wants them for that car -- go figure).

off topic, but love that movie car man.

on topic ... I dont have any underside exhaust photos for my three fusie squads '71, '72, and '73 I still own. I did not need exhaust work on the '73.

I do know the dual tailpipes on all three cars have hangers more or less placed where @73Coupe said. two clamps per pipe, above the axle and less than a foot from tip.

the "bends" may be of course be different to account for whatever DID change (NVH stuff, bumper impact standards in 73 MY, flow considerations for emissions, etc) over those years (different arc lengths, bend radii, etc, over the the post-muffler length) on the underside.

I still maintain I would not expect (if you keep the OEM pipe diameter) the pipes to be materially different.

youve got a good plan for your intentions. "break a leg" on that hamster wheel chief.

I just got a shipping notice today. Ahead o' schedule!

The TTI systems for C-bodies cover many years, the only change was manifold head pipes over the years. I had only one issue with the TTI and that was fitting the longer Imperial mufflers. Very happy with the system.
Waldron's exhaust should be able to help you. Not saying they will. You could get TTI head and H pipe then tail pipes from Accurate exhaust and supply your own correct mufflers.
