'42 Tudor Sedan......was thinking I would like to put on 2" dual exhaust....(or possibly 1-3/4") using the stock manifolds if possible....and running the tailpipes all the way to the bumper......looking for feedback from those that have maybe done this already and how difficult with some of the clearance issues I have heard about. Also, I am pretty sure I have decided on either Brockman Mellowtones or Cherry Bomb's so I would be interested in some thoughts on that if you care to share. Thanks !

I knew a man in 1961 who built an dual exhaust system for his 1934 Ford Tudor using galvanized plumbing pipe and 45 degree angles and elbows with Gambles hard ware store glass paks. His engine was a stock V-8 flathead and that is why I have replied. The thickness of the pipe gave a very pleasant very appropriate sound to his flathead. Now if I were to say you should have the tailpipes exit laterally close to each other so on a cold day the vapor exhaust would swirl contra-rotating to each other that would be very 1942.

It can be done, you need to fabricate a j or u shaped pipe with flange comming off of the drivers side manifold. The block off the cross over exit on the passenger side manifold then complete to the rear of the car. Much better to install cast headders desinged for duals. I have used Red's Headders [tubular] on two different cars & they were great, but cast ones can be had too. Post this on The Ford Barn, lots of help there too. mike

Shop around in your area for a good exhaust fabrication shop and have them install the complete exhaust system for you. It will be more expensive than doing the job yourself but will save you lots of time and frustration. They will solve the clearance problems for you.

I used Red's headers and Brockman mufflers. They will make any size and length . I love the tone of them. I have seen the set up for using the stock manifolds once in a while on E bay.

Go with the 1 3/4" pipes. The 2" pipes may interfere with the clutch.

I had 1 3/4” steel pipes done at a local shop, i supplied 18” steel packs from Mac VanPelt. The pipes were a bit more than a kit but the tucked in really well and looked like they belonged. It had a nice mellow sound. Dyno test showed headers are not necessary so I used stock single outlet manifolds. I think they were from late 40s flathead. Tim Downtown, Ca
