master cylinder vs exhaust heat

Im in the process of doing the exhaust on the '55 but not sure how I should be routing the drivers side off of the manifold. I have installed the master cylinder and there is room to run it straight back under the booster when it is aired out but am a little worried about heat. I will be wraping it with header wrap as well. I could also angle it toward the outside of the frame and back in after the master cylinder. What have you guys done? Here is a pic of the setup.

you might try some heat shield under the Master cylinder - the type they use to wrap starters to help in close heat situations

That's where the stock exhaust was run under the stock system. I wouldn't/ didn't. Mine is run like that.

I think I would angle them inwards just past the trans and keep them tight down the length of the driveshaft to a spot where you can angle them out to your mufflers.

Re: master cylinder vs exhaust heat

Make sure before you wrap anything with header wrap, that there isn't a coating that needs ventilation or needs to be able to cool down or simply needs to burn itself off. The wrap will make your header hotter internally retaining heat and if it has a cheap coating on it, it can ignite. Been there, done that (luckily in the driveway).

Re: master cylinder vs exhaust heat

The wrap would just be on the bare down pipe under the master cylinder not the header itself but that is a good thing to know.

Re: master cylinder vs exhaust heat

Make a sheet metal heat shield to go between the exhaust pipe and Brake unit. Forget the wrap .

If you've seen a car with AirLift bags installed in the rear coil springs AirLift supplies a heat shield you form and clamp to the exhaust pipe.

Its simple to make one from flat sheet metal. Cut a piece 5" or 6" wide and as long as you need, now make two cuts about 3/4" apart off the center line at the ends about 1 1/2" long. Bend it 90* and 1/2" bend it 90* so it forms a leg. Clamp it to the exhaust pipe with 2 screw type hose clamps.
