Dual exhaust for stock manifolds

[jrvariel48]

In my 1935 coupe I have a set of stock exhaust manifolds on a 46 59AB motor (pictured)
Does anyone make a dual exhaust set up for the manifolds or is this something for the muffler shop to fabricate?
Thank you, Joe

Get a local muffler shop to do it. Be sure they allow for clearance past the clutch pedal.
Also FYI, they are identical from the muffler back, and should lay flat on the floor if bent correctly.

IF the 35 is like a 40 in the master cylinder/pedals/frame area good luck trying to fit an aftermarket piece in that area.
I suggest a patient custom exhaust man. Lot's of tricky bends needed.

Hi Everyone. john warden, A stock 35 has mechanical brakes.

[john worden]

OK thanks.

Yep, have a GOOD exhaust guy fabricate the system. I say a "good" guy as 35 - 36 Fords can be tricky to do nicely. Many guys bring the front pipe out beneath the running board. Yeah, a lot easier to get by the battery and clutch pedal, etc. but looks like poop.
Done correctly, this system can be installed nicely.
Might I ask why you want dual exhaust? If it is just for "looks" perhaps you should consider splitting the exhaust pipe before the rear cross member and running two tail pipes back. You'll get the "look" w/o any complicated (necessary) work.

Kube,
I should have mentioned the dual exhaust was already installed but with steel tube headers. I removed the headers because of the interference with the 39 steering box I just installed. Now I'm wondering if the stock exhaust will interfere with the box. I opted to re-drilled the hole on the box instead of changing the mount!
Anyone have this set up or another option??

I remember back in the 50s you could buy a dual exh set for the early flathead using the stock manifold from Sears Robuck. Also you could buy a dual carb intake. That was the first things I bought when I was a teen. How about Reds Headers. Walt

I bought my duals for stock headers @ Hershey in 97 from Waldrons Antique Exhaust -perfect fit. Don't know if he is still around. Try 800503 9428 or 616 4677185

Just to make us all feel old and decrepit...I noticed a 1959 Hones Charley catalog under my desk.
What you need is 12.95 without mufflers, 23.95 with your choice of steel or glass pack mufflers, plus they sell everything for the dual side separately in case the stock exhaust is still good.
A flange-and-U bend header kit is 8.95, don't see headers but everyone still sold the Belonds then, probably 20 bucks or so.

A little off topic, but I always was intrigued by the way the driver side headpipe on an aftermarket dual exhaust kit for '49-'53's looped up from the front of the exhaust manifold and dove back under the firewall. I always wondered how efficient that was.

Still a good chunk more efficient than the exhaust ports it just came out of!

I tried the stock exhaust today with a little grinding and it's not going to fit. So I tried and tried to get the steel tube exhaust manifold to fit the drivers side and unless I beat the crap out of it and collapse the center tube it will not fit. I'm hoping Red's makes something that will fit. Anyone have a similar set up? ( '35 coupe, '46 AB motor,39 box with the top hole drilled out)

47 merc,reds headers,dual corvette style M.C. I thought m.c.and brake lines were too close to exhaust. m.c.had outlets on both sides,should have used the ones on pass.side,instead of drivers side. I put a 90 degree bend onto header,welded a piece on it to point back,and under the frame until it cleared m.c.and lines. hack job,but functional. normal routing from ahead of the muffler,to rear. Not a restoration,or show car,and setup can easily be changed if any problem arises. Pedals were installed after this,and clutch pedal contacts the bend slightly about 1/2" before pedal is on the floor. I'll figure how to dimple the pipe without taking everything apart.

I know you were specific about stock 35 headers - but just for giggles - here is a close up of a 39 steering box in my 35 Coupe chassis (1/4 inch clearance to the Fenton header) as well as a shot of the custom exhaust running past the 39 pedal assembly and master cylinder conversion and out toward the back. The system is designed to run either straight pipe (shown here) or with mufflers with a simple quick change of 4 bolts on each side. Turned out that the sound was so incredibly loud I switched to the mufflers. Just wanted to show the solution for my 35 by a very talented pipe man. Hope this gives you some encouragement as to the art of the possible.

Ya' know...I never get tired of looking at Peter C's coupe. Thanks for posting those pics.

That's one beautiful chassis. Look how straight those rails are and nice dual circuit conversion too.

Peter, Can you tell me about the mounting of the steering box?
Did you change the frame mount or redrill the box?
Thanks for the great pictures!!

A stock 39 Ford mounting bracket was used - to get the clearance needed ... we did slightly notch the lower chassis rail on the edge facing the bracket by approx 1/4" so the bracket could be inset a bit deeper into the frame and the box eased slightly away from the exhaust manifold. Hope that helps.

There is one consideration that is missing here. In JWL's book, he tested the results of dual exhaust systems, including headers. The result was no noticeable gain in power. But I love the sound it produces.
