Re: Loud exhaust
A lot of folks mention the H-pipe. They are used in a lot of dual exhaust systems to balance out the pulses between one side and the other. The firing order of a V8 can cause some uneven pulses if there is nothing to balance them out. The little passage in the block that provides heat for the intake manifold will do the trick in some cases but some folks put pennies in there or there can sometimes be carbon blockage.
The cars of the fathead era were not well designed for a cross over pipe so it's not all that easy to incorporate one. The sound is smoothed out a lot with good balance. Even some header back systems on later cars with OHV & OHC V8 engines incorporate a cross over just for that purpose. |

Re: Loud exhaust
My 52 F1 with duals and smitys was loud. Then I insulated the whole interior and it’s now it’s fine

Re: Loud exhaust
I used 22” Smittys on the first dual exhaust setup. I was disappointed with the sound. Sound was restricted and didn’t have any of the chactoristic flathead V8 sound. In defense of Smittys, it may have been a product of a poor pipe installation. Not loud and no drone but not a good sound.
The new system with the Monotones has a clear, crisp sound that really amplifies what I call a “corkscrew” sound of the Ford flathead. I love this sound. I just need it to be a little less so that my wife will enjoy it too. Ricosan |

Re: Loud exhaust
My choice, shows up on post 19. Not sure? Find a Harley biker that has been around for awhile.
Good Luck

Re: Loud exhaust
Dad put headers and Smithys on the Phaeton, and I don't think it's loud at all. (no H pipe) Actually sounds pretty good! Does your car have the exhaust run all the way out the back? If it exits under the car, it will resonate and sound a LOT louder from inside the car.
The LONGER the an absorption type muffler is (glass pack) the quieter it will be. If you have a choice between shorter and longer mufflers, choose the longer one if you want it to be quiet. It's surprising just how much of a difference it will make.

Re: Loud exhaust
MY '47, stock motor, fentons, 1 3/4" pipe, 16" generic glass packs.....sounds good to me and you can talk just find inside. The engine is cold also.
Maybe 2 small resonators for your '34. https://youtu.be/KN4vtJlOOHQ |

Re: Loud exhaust
I like the sound of a plain old gutted muffler on a flathead. Quiet and mellow.

Re: Loud exhaust
My 33 coupe has just a resonator on each side. It had a lot of reverb inside when the pipes ended short underneath. I extended them back to just in front of the rear wheels and it sounds pretty nice now.

Re: Loud exhaust
If you really want quiet, why not revert back to the single exhaust system? The crossover pipe serves a similar function to an H pipe in dual exhaust. And, there is really no difference in the HP between single and dual exhaust until you get into the larger cubic inchers and higher rpms.

Re: Loud exhaust
UPDATE
Well, I don’t know what to say. I took my wife out for lunch. I had the back window unzipped as the temperature was warm and you can’t see anything out back with the window zipped closed. I tried to keep the engine as quiet as possible as we left the house. I braced myself for the coming tirade about the loud exhaust. I got down the street and around the first corner. Nothing from my wife. After about five minutes still nothing. We did the entire ride (about 15miles) with no complaints. I love the sound I have now and my wife isn’t complaining! I think that secretly she likes it! Ricosan |

Re: Loud exhaust
I can't find anything on "Monotone" mufflers. Who makes or sells them?

Re: Loud exhaust
Glad it worked out!
I'm not one of those; if it's too loud, you're too old. Lots of quiet-ish cars out there that can rip a hyundai/ford/etc with a coffee can or straight pipe. Loud doesn't always make a car fast on the street I do like some rumble though. Always.... run what you like!!! Last edited by Tinker; 03-04-2019 at 09:53 PM. |

I agree. My only thought on dual exhaust is heat removal. |
