Can anybody snap a quick shot showing how their tailpipe is hung from the frame rail aft of the rear axle? I'm getting set to redo my exhaust from the muffler back, OE-style tailpipe for my model year isn't available so instead I got a newer style introduced in '76 apparently, where the tailpipe does a 90-degree bend out behind the rear wheel instead of angling back toward the rear corner.
Diagrams in my FSM show the older style only with a special hanger.
I have hangers for the newer style but it would be helpful to see exactly how they're supposed to be installed. I can probably figure it out on the fly, but I'm no exhaust expert and a photo or two would be helpful. Thanks. An FSM diagram would work, too.
And exhaust installation tips welcome as well.

Megunticook,
Give me a couple of days and I'll take a picture of the way my '72 (which is now on E-bay) is set up. It has stock single exhaust except for a glasspack muffler in place of the stock "metal can". The truck is currently in my barn, a 1/8 mile walk away across a soggy field, but I have to go over there by Monday.
Good grief, man, don't they have any good exhaust guys who can bend and swedge heavy-gauge pipe up there? You can't throw a rock without hitting one down here in rural North Carolina! I have never had a problem getting an exhaust fabbed-up from scratch down here (unless you want 'em to make a Y-pipe or an H-pipe); I can't believe that Maine is that different.

They do, but the last 2 times I had my exhaust system replaced it was by 2 different local shops and I was disappointed both times. One didn't bother to replace the tailpipe and just did downspouts (I have dual), I guess they figured they were saving me a few bucks, I don't know, but when I picked up the truck it was about twice the decibels (at least in the cab). I should've had them redo it then and there, but I didn't think it was worth fussing over.
The second time I went to another local shop, dealt with the shop owner, and asked him specifically to replace the downspouts with proper pipes. When I went to pick it up it was like we never had the conversation. I questioned him about it, he just shrugged, and again I figured instead of making an issue of it I'd just never patronize the guy's shop again. He'd bent over backwards to give me an inspection sticker (body rust) so I didn't think it would do to bust his balls over the exhaust.
The cab drone was just as bad the second time.
So this time I'm doing it myself, with proper OE-style mufflers and full tailpipes. I've really had it with paying people to do sub-standard work on my vehicle.
The Walker stuff I ordered seemed like decent quality (muffler looks just like the OE ones in my FSM, is the Quiet Flow line, and this particular model 21169 is supposedly "Heavy Duty arc-welded construction, recommended for commercial use"), price wasn't bad.
I'm thinking I'll be a lot happier out of this setup and maybe get more life out of it, too.

Megunticook,
Here (finally) are the promised photos of the single exhaust system on my ‘72 (I hope).
#1 shows the exit location behind the right rear wheel; #2 shows how the tailpipe hanger is bolted to the frame; #3 shows the center hanger bolted to what seemed to be a reinforcement of the frame crossmember which is directly ahead of the rear axle (R.H. longitudinal frame rail is shown diagonally at upper left corner); And photos #4 and #5 show two different views of the forward hanger attached to the triangular bracket which is bolter to the R.H. frame rail just behind the center crossmember (one crossmember ahead of that shown in #3).
I am sure you are anxious to get your rig back together so that you can push all of that snow you will soon have up there in Maine!

Thanks, #2 was the one I was looking for but interesting to see the others. My FSM diagram doesn't show a hanger above the axle--interesting that you have one there. Makes perfect sense.
Anyway, it confirms how the tailpipe hanger is set up.
Your tailpipe hanger and configuration matches what I got from Walker, but it's different than the '73 and '74 FSM shows. If the Walker catalog is accurate, that right-angle style tailpipe didn't come in until '76. Interesting that your truck has it. Is that the original factory exhaust? Hard to believe...but I guess they don't have road salt in North Carolina!

My original exhaust was the same way on my '72, but I chose to take it off when I dropped the motor back in and went with duals and flowmasters exiting just before the rear tires. :rck: It sounds good at idle, but it is really loud in the cab when driving, I may go back and redo it again... still up in the air on that one:rolleyes:

Good idea there, I have the original exhaust on mine and I don't get the noise in the cab. Of course I have the two 12's behind the seat cranked up most of the time anyways. Either way, when I sit at a red light and spot one of those ricers next to me, y'all know I am going to rev that Dodge engine and make them wet their pants :D

No, Megnticook, the original exhaust wasn't even on the truck when I bought it. Actually, this truck came from Flat Rock which is in the mountains -- and they do indeed use plenty of road salt up there!
It had nothing but a muffler and a dump tube which exited beneath the truck just aft of the cab. I had the system in the pictures hung from the factory brackets about ten years ago by a local pipe shop.
As far as the tailpipe turn-out is concerned, I never questioned it. The pipe man used a set of pattern cards to bend it up; perhaps he used a pattern which applied to a later truck. I didn't care because he did basically as I asked: exited it behind the right rear wheel, instead of running it straight out the back like most of 'em do. The pipes are so much louder that way and create so much scavenging, I often wonder why so many guys insist that their pipes be installed that way. I guess they feel that all of that racket compensates for some other shortcoming -- or they want to collect core samples from every embankment they back into . . . . :D

Well the guy that hung yours Jeff must have known what they were doing...I'm going off of memory, but I'm not that old yet! Anyways if my memory severs me correctly the pipe on my truck, when I took it off, was hung almost exactly like yours in the pics. I guess the dealer could have changed it out, or my grandfather may have had it changed out, not sure about that. I'll look again underneath the truck, I left the hangers in place just in case I wanted to go back to that set up, that way it would be easier to reproduce the layout.
I never have figured out why so many trucks have the exhaust going out the back, if you are towing anything and running a bit rich you are going to coat everything that you towing! I prefer to exit out from the side personally!

That's how the '73 and '74 Dodge FSM shows it--out the back corner. Even had a special bracket. I think the side tailpipe came in in '76. Glad to hear it's a quieter and more practical design.
One question, though--does it matter which side goes "up" on a muffler? Mine don't appear to have a weephole anywhere, and I would put the welded seam down (writing on top) except it looks like it may fit better upside down. Any "downsides" to that (yuk, yuk!)?

My 82 has the exhaust running straight back and to the right side of it, no bends in the pipe as far as I can see. Since the hanger did break in the back, I ended up using part of a fence. The part that holds the fence to the metal poles.

M-cook,
I doubt that it matters which side of the muffler faces up. Not all of them have weep holes to drain the collected moisture, I have noticed. Just install 'em the way that they fit best, I guess.

Q: Why can't we North Carolinians keep our exhaust from falling off our vehicles?
A: Because copper theives keep crawling underneath 'em to steal the wire which holds the pipes up!

C1DoG,
Aw, heck: I thought you meant that you used a piece of that heavy-gauge stuff which looks like bailin' wire on steroids! Those clamps you showed almost look like they could pass for O.E.
Which color did you choose?

and from the looks of it, it looks like it is time to look at getting new exhaust and such. I was thinking of replacing header pipes all the way back. They are all original.

ok y'all. I am looking for a good exhaust kit. Anybody have any clue to where I can get one. Would I be good going with JC Whitney for all the parts?

10-06-2008, 08:51 AM
I haven't used this one but it doesn't sound to bad of a deal to me....
I'm not sure if I want it to go dual or keep it to the right side. Will it affect fuel mileage(i.e. better ), if I went with a dual setup? It does look like a good kit, Summit is a good place for parts. From the looks of that kit, I would still have to get a catalytic converter for it though.

It would help with the HP (you main gain 2-5hp), as far as MPG goes that depends on your foot! I'm only getting about 8-10 on my truck, but I tend to have a heavy foot:cool:
You can always just go with headers, a "Y" pipe, a universal cat and high flow muffler... Depends on what you want it to sound like as well, if you want to sound more like a stock truck go with a OEM replacement muffler, it you want to have a deeper and louder sound to it go with the Sonic turbo from summit, it has the same design and quality of a flowmaster but it is a lot cheaper.

cool, I will give that a check, as to the exhaust, I want a good rumble. I have a tendency to rev the engine while sitting next to a ricer. And always the same look when I do. Duh! :D Since I am on a limited budget, I am going to slowly pick up the parts and then once I have them all. Then put them on the truck, sounds like a decent plan to me.
