A good muffler shop that is equipped with a hydraulic bender should be able to fish 2-inch pipes through the frame openings. The larger diameter pipes will give a more "mellow" tone, and the stock diameter pipes will be a little "sharper". There is quite a bit of room in the frame openings for even bigger pipes. The area that can be of concern however, is the left hand "header pipe" leading from either a stock manifold or aftermarket header. This pipe must clear the clutch and brake pedals when they are fully depressed, and of course doesn't exist in a stock single-pipe installation. If your 36 has hydraulic brakes, it would be a good idea to bleed-off fluid to allow the pedal to go all the way down prior to measuring for the above-referenced interference issue. If they are stock mechanicals, then make sure you temporarily back-off the adjustment to check this clearance. The last thing you want to happen is to apply the brakes in a panic stop situation, and find that your brake pedal is blocked by this non-original header pipe.

I don't remember where I got this picture but it was a dual arrangement on a 36 coupe that ran a left-hand exhaust side from the crossover pipe. This is a really neat idea. It avoids problems with the pedal assembly and the floor-mounted battery. Tom

Great picture! It illustrates one of the big the problem, the battery. To run the duals straight back from the headers, the battery under the drivers floor is the problem. The picture illustrates one good solution. What I did was move the battery to a spot closer to the drive shaft under the left rear seat. This way the two pipes were appoximately the same length (I thought that was important for equal back pressure, but maybe that doesn't matter either) The other area of concern was getting past the steering box and pedal assembly, but iwth th battery moved it worked better. I have two old cherry bomb mufflers that emit the sweet flathaed sound without being loud or offensive. Even at highway speeds they are beautiful and quiet. Paul

The original '36 exhaust had 2" diameter pipe for the muffler inlet exhaust/header pipe and 1-1/2" diameter for the muffler outlet extension/tail pipe. Based on reading about the personal experiences of others, who have installed duals on their Early Ford V8's, the maximum diameter to use for tail pipes from muffler back is 1-3/4" for best flow/sound, etc. That's probably what I will use although I plan to check with Red's Headers to determine what diameter tail pipes they use on their '35-'36 dual exhaust kits.

If you can detect much, if any, difference in the sound of dual exhaust between 1.5 and 2 inch pipes, you have better ears than I have. If installation interferes with the location of the underfloor battery box, consider using an Optima battery. It is half the size of the usual lead-acid type, and can be mounted in any position. They used to say that Guy Lomabardo's band produced the "sweetest sound this side of heaven". Nope. A good set of glass packs on a flathead fits that description!
