  • Heat abatement in your Model a

    I tried a little experiment in my model a my old muffler was a tinny cheap thing so i bought a new aries muffler. I wrapped this muffler with the header wrap which you can buy at auto parts stores. I wrapped the whole muffler starting just below where the muffler clamps to the manifold and went down all the way to the muffler itself and did not wrap the bell part but started wrapping again at the front and wrapped the whole muffler. They make stainless ties to hold all of this together. Out of curiosity I then place plastic zip ties around this in various places just to see how much difference this made. The first zip tie just below the manifold clamp did melt but stayed in place 3" below that it did not melt at all mind you i double wrapped this area. These zip ties were as good as when I put them on. My thinking here is two fold First I wanted to stop the heat around the carburetor and possible vapor locking but most of all i wanted to stop the heat under the floor board. I drove this car yesterday 20 miles and am quite happy with the result. I really did not like those shields they sell looks like a rattler to me. I am also told that wrapping these also helps draw on the exhaust from my buddies running sprint cars and trust me it gets hot down there in one of them. If you drive your car this seems to work pretty good show cars like Mitch"s would lose points. Just thought I would throw this out there I am no expert just an idea I had and it seems to work.

    The wrap will likely shorten the life of the muffler.

      Of all the information posted through out the years for heat infiltration this plan is one that i don't remember reading being done on an A. It seems like a sound plan and should make a huge difference IMO. Can you post a few pics of the completed job? It may promote rot as i mentioned on your last thread about this

        I am not quite as concerned about muffler corrosion. Headers seem to do just fine with it. I believe they make an all SS type of zip tie that could be used.
        I have a section of my tailpipe on the touring wrapped to better shield the speedo cable from the Mitchell.
        It would help with hot gas extraction

          I have read if you wrap your headers with it that voids the warranty for corrosion

        That i did not read will have to go to aries site and look at that or maybe give them a call and see what they say. Thanks Mitch.

          I didn't read it from Aries and do not know what their policy would be. I saw it on other general racing header sites

        Ok may have to rethink this seemed like a great idea at the the time but at least i do not have dex-cool in anything.

          Fascinating experiment. Do most auto shops carry that stuff?

          Heat insulation- aluminum?
          by wayne1230cars
          Wondering about using a piece of aluminum roof flashing on the outside of the passenger side floorboard. The floor board already has insulation on the inside as well as a firewall insulator. Do you think the aluminum would help in reducing exhaust heat?

          muffler and tail pipe

          Is it better to buy one complete from a supplier or have one made at the local muffler shop?

          connecting muffler to exhaust pipes without welding
          by ClaudeC
          Where Can I purchase couplings that can be used to connect muffler to exhaust pipe without welding? I assume it would be a thinner fitting that inserts into the muffler and exhaust tube then is clamped in place.

          Muffler question
          by plyfor
          Our muffler when tapped on the outside creates a clunking sound that may indicate something is loose inside. Could it be the baffles? We replaced the rear tail pipe clamp with a flexible type mount so there is no effect from that.

          HP Stainless muffler
          by AL in NY
          I need to buy a new muffler and was looking at the HP Stainless Steel Muffler that Snyder's sells. But I have one question. Has anyone installed this muffler and how much louder is it from
          stock? Is it the Aries muffler which has the same part number.

          Keeping the exhasust heat down in your car.
          by BNCHIEF
          I have seen the heat shields vendors sell and kind of thought they would be nothing more than rattling vibrators under the car. I did something different that we used to do on sprint cars they make a high heat wrap napa and o reilly have it and I wrapped the entire exhaust and muffler with it it is help in place with little stainless ties i would post a picture but it is under the car and would...

          Why in the H does the muffler not line up with the exhaust manifold?
          by Rob Doe
          When I had my car as a 15 year old, I had difficulty with the muffler not lining up to the manifold. And I remember very well the clearance problem with the wrench on the back nut and the interference of the the oil return tube. But this time I had a jack to hold it up almost in place. You'd think it would have been easy. Mr. Shinn's video made it look so easy. When I finished and grabbed up my tools,...

          Muffler Questions
          by dmdeaton
          Ok, our roadster came to us with a stainless muffler and pipe. I have slowly been stripping off most of the period style accessories that came with it. Too much bling. After helping a friend swap out engines in his, I noticed the nice Model A exhaust tone with his running. Mine doesn't sound like this, not bad, but not the slight whistle at idle? What muffler setup is a good stock replacement?
