Period Correct Exhaust Build
 

Who does what?
I am building a late 1940's style 1932 Roadster...with a Flathead and dual 97's.

I need to design the exhaust.
I have Red's Headers to start. (not as period correct as making my own, I know)
I am interested in knowing what anyone may have done to create a Period Correct Exhaust from the Headers on back...
- All pipes slip fit?
- System held by hangers and not welded to frame
(Anyone sell vintage style hangers?)

Thanks!

All welds should be made with coat-hangers and a torch. ;)

How about using that fexible pipe they used back then!

Don't forget your tomato soup cans for minor repairs

Re: Period Correct Exhaust Build
 

There are probably dozens of "period correct" ways of doing it. All depends on which way you want it. Maybe something like this.

My dad was born in 1918 and this pic was taken before 1941. Had to be between 1938 and 40. Notice how the tail pipes were hung from the rear bumper on his 32 3 window. That is period correct.

And where you going to get duds like my dad was wearing. Notice the Road Rebel plate on the back. A Los Angelos club.

They use to put V8 tomato juice in a can that seemed to be just the right size and a heavier guage,this was pretty technical stuff . I think I used at least one of these to fix the damage done after installing the dash controlled exhaust cutout from JC Whitney that invariably would not completely shut and leaked.

Me and a couple of my buddys when we were 16 jopped a 32 5w and welded it all back together with coat hangers. My mother always wanted to know what happened to her coat hangers. Walt

Notice that they run beneath the axle . Makes for some clunks when crossing
RR tracks.

Detonator posted this picture last month. It was his uncle's car and the thread was "Show us your avatar" or something like that. Doesn't get too much simpler than that!

Who remembers the 'scavenger" pipes of the 60's?? Welded them to the 6 cyl chev mufflers (deuce coupe with an olds),flex pipe at the front off stock exh manifolds. duals, gave a "strange" sound.

Re: Period Correct Exhaust Build
 

My 33 had the remnants of pipes still in place. there was flexible pipe in there, the mufflers were mounted straight to the floor and the remaining tailpipe was mounted off the frame.

If that's period correct I'd rather do it a little more carefully and at least get some rubber in there.

When I did do mine I made it up from an exhaust meant for another car and I did gas weld it, so maybe it is still kinda old school.

Mart.

Did not know that,Thanks Phil

Run a pair of torque tubes under the axle. Pennies in the crossovers, no mufflers.
Hoo Yah! Rumble like ya mean it!

Re: Period Correct Exhaust Build
 

Dont forget ripple pipes! Just heat and bend, the ripples actually look quite cool.

Re: Period Correct Exhaust Build
 

All water pipe with screw fittings. Very stout.

Re: Period Correct Exhaust Build
 

Use 1934 drive shafts....you will never get a better sound. That is what I have on my car.

Re: Period Correct Exhaust Build
 

x2. That's how I did it in the 1970's.

Re: Period Correct Exhaust Build
 

Hahaha... maybe it was a kiwi thing? :cool:

Re: Period Correct Exhaust Build
 

Actually coat-hangers for gas welding is a "Jonny-come-lately" type of welding rod...
Baling wire, i.e. mild steel tie wire was the welding rod of choice in the muffler (Hot Rod) shop that I worked in during the very early '50's..
We used OXY/AC to braze all of the split manifolds we made..
Prior to 1953 I made spilt manifolds and/or headers for most of the deceased brands of automobiles.. Chrosley, Nash, Dodge/Plymouth, Packard, Pontiac, etc.
Difficult bends were made using flex pipe.. or U bends cut and welded together... Pipe benders were unheard of...
Of course if a customer had big bucks we would order a set of "Belond Headers..
I still have a pair of Belond Headers hanging on the wall of my garage.. Bought them for my '36 Ford, put them on, took them off, all within the same day...

Re: Period Correct Exhaust Build
 

The preferred torque tubes for exhaust tips, i.e. from the axle to the rear bumper were the tapered tubes, '36 and earlier.. They are close to 2-1/2" IN the center, tapering to about 1-1/2" at the end..
The ends near the rear bumper were generally cut on an angle... Made the "Boom Cans" look bigger... Been there done that...
I can still remember the first spit manifold I made, it was for a '38 Chevy 4dr..
Burnt a hole in the rear portion of the manifold, brazed a piece of water pipe into the hole, attached a length of flex pipe, brazed to the pipe extension, ran the flex pipe out through the frame,tying same in place with baling/tie wire... Had customers lined up at the shop wanting us to do their cars...
And people think that "Old School" is/was so neat...

Re: Period Correct Exhaust Build
 

I still have a pair of those, but always wondered about the flow patterns.

Re: Period Correct Exhaust Build
 

Haha... probably made no difference. We tend to overthink the capabilities of the flathead..... eg: in dyno results there are no difference between headers and stock manifolds. Now that goes contrary to what most of us would think, but there it is in black and white.

Most likey traditional exhaust were whatever you happened have have around and could make work. I can remember 45 years ago laying in snowbanks trying anything that would work under an old car to get it to school the next day. So I never meant to poke too much fun with my soup can idea but it sure saved my ass a few times, that, some wire, and those modern expensive hose clamp things :)
