Project ’37 Ford Cabriolet, exhaust

Project 1937 Ford Cabriolet came with a stock single exhaust and it was hitting the frame so I had to remove it anyway. I decided to start from scratch.

These are the old pipes, they look a bit tired.

I kept the flange and went to work.

Look, a 1937 Ford exhaust. What, you can’t see it?? Well, let me show you.

Thrush had an ad in the sixties that said: Put a Thrush on your pipe and…smoke it! I doubt we can smoke anything with this stock flathead but I am counting on some good flathead sound emanating from the dual pipes.

I could not resist adding for the electric cut-outs. I am sure with these small glass packs I will have a nice rumble out the rear but there might be a time when an uncorked flathead will be music to ones ears. Off road of course. They come with wiring and one switch that opens both simultaneously. Yes, I did test them, they work on 6 volts as well. The switch looks like a modern power window switch so obviously I would have to hide it under the dash.

It is great to line up tubes when you are going to weld them together. I tacked everything together first and then did a test fit on the car.


1937 Ford Cabriolet exhaust cut outs

The exhaust cut-outs are designed for 3 inch exhaust pipes. The dual system I am building is based on 1 1/2 inch pipes so we have to be a little creative.

The mufflers and exhaust cut outs needed to be compact so I came up with the idea of cutting down the muffler and insert it in the Y-pipe.

Here is the compact solution, the world famous Super Sonic Muffler Cut-Out Device.

The last 36 inches of the exhaust is stainless so I polished it to chrome finish. Now I don’t have to worry about adding chrome tips.

1937 Ford Cabriolet exhaust paint Once all welded up I coated everything with high temp paint. Yes, I wear a respirator even when painting with spray cans. Most paint spray cans contains nasty stuff. You only have one pair of lungs.

Here it is. A complete 1937 Ford dual exhaust system.

1937 Ford Cabriolet exhaust insulation

It is tight on the drivers side because of the steering box. I have to dip down below the frame and that makes part of the exhaust close to the master cylinder. I added insulation to the pipe to keep the heat away from the master cylinder.

Well, here we are. All done. A drive around town confirmed a nice mellow note. Also the restored plate is in place and a vintage frame adds the finishing touch.

Ready for the up-coming Ford Meet.
