James, I'll try to get a pic up for comparison.
Thanks! |

Ok Greg, I'm going for the compromise - Punch the loose one out and do the same to the other side for balance. There should be several baffles inside so you will end up with sort of 2/3rd's muffling!! The mufflers were always on the fragile side so another layer of glass and epoxy around the outside wouldn't hurt.

BuffaloBFN,
I might have one. What does yours look like? I have the originals off of my '78 Martinique. One of them lost its baffles and I couldn't find a single original replacement, so I ordered a new pair from SECC. The new replacements are not exactly like the originals, but they seemed to sound and perform about the same. The originals are light blue. I can't remember the diameter, I'll have to get them out from under the house. |

Mercury makes a beautiful set of baffles that mount right on the transom, they are about the size of a coffee can cut in half with stainless tips that go out the back, they are for 3" hose. they quiet the boat just enough and keeps the rumble. I installed them many times on the nusance boats because of the complaining neihbors.

Mine are in the floor. I probably won't take them out, but wouldn't mind if they were gone. Mine, just like all the othere 454's, sounds great, even with the mufflers. You said "one" of your baffles was loose? If you knock one out, wouldn't you have to knock out both for balance? Just a thought. I agree with the thought that without mufflers, it still won't be as loud as the Baja's. Steve |

Good idea. Mufflers with no baffles. Years ago I remember my older brother's friends buying glass packs and pouring kero in them and burning the baffles out before installing them on their cars. It improved the sound.

I've barely started on the stringers, so I have some time. If I can't round 1 up, mabe I should knock the other baffle out? There's not much to it. It would effectively be a straight pipe with a 3' expansion chamber. You're the engineer though...whatcha think?

Greg, Cut the one with the loose baffle open and repair/resin it back together. 10 db is about what I'm finding for the sound reduction but that's todays mufflers and not the old ones. It is not going to sound like the Baja.

We very much want to make the trip, but we also have a busy spring coming up. If our wedding doesn't completely break the bank, we'll be there! |

Hot rods are hot rods and need to be loud but pulling the kids around the lake for 8 hours without mufflers is too much. I've got mufflers on mine for that exact reason otherwise they'de be gone.

Priceless! 
How many of you are running a bfn without mufflers? Tull, are yours in the floor or not? I live on a peninsula that has about 50 houses on it...at least half retired; and I have a neighbor with a straight pipe baja that shakes the windows(literally). I'm in much better standing with my neighbors than he is...and would like to keep it that way! I've also seen barney hassle him several times while we ride on by. Bottom line, I've gotten many compliments on the sound of my boat, and people scrunch up their faces when the baja fires up. Peace, Love, and Smiles! |

I agree! If she doesn't LOVE the boat she will NEVER make it with guys like you and MINE! Personally, I Love that old boat rumble and all.
She doesn't need mufflers and Billy doesn't need a raincoat. Pete, do you need to stop the boat? We don't!!! The Boat Nurse |

If the girl doesn't love the subtle rumbling of that engine while on that slow cruise, time to trade her in.

Thanks Bruce, Ill take that as a compliment.
Ive got no opinion here, as some people like their boats quieter than others. I just happen to like mine loud! Greg, what's been posted above is correct- its not overly loud inside the boat. No problems communicating at idle. When you get the chance to hear the boat from the end of a rope or on shore, thats when you find out how loud it is. |

They had to come up with the "duck" name because the people in the Atlanta area couldn't pronounce "duct".
Greg, You don't need to run hose all the way. I think the fiberglass exhaust pipe is cheaper. Plus, the fiberglass would be sort of half way original. I think you can forget about copper these days! |

As long as you're not riding in the back seat, there's barely a noticable difference.
On those mid night rides you'll be idling anyway so it won't matter. |

I remember in the 70's when the boats were starting to be equipped with the fiberglass 1st generation. You can tell a difference but not that much.
A "closet duct (duck) tape junkie" Wow, now that is a real low blow!! You do have me pegged. I do not have any duck tape. I did need some this last summer when a tree branch poked a small hole in the vinyl of my "instant garage". I had to borrow some from my son! |

Next time you say 'keep it original' to a newbie, I'm gonna tell him you are a closet duck tape junkie!
So, if I cave on this and spend another couple hundred on 10' sections...  ...just how much louder will it be?

Never bothered me when I had the 70 Barracuda with the Holman Moody! With the exception of a straight pipe rear engine, there is nothing that sounds like the H/M's. You need to stop the boat anyway if you have any "plans" on that midnight ride. |

Greg, if you're that close I've waved to you before. I'd like to hear it, but I think I'll stick to my guns. I'll give the fanatic a day or 2 to respond...I kinda thought he'd be first instead of all of this grief?!!? LOL |

Greg, I'm going with the rest of the guys on this one! You don't need them. I've been around too many classics. It'll sound great. The fiberglass things were mufflers. Keeping it original - No one will ever know what was supposed to be under that floor. That of coarse is the exception of several hundred people who read this thread!! |

Greg,
The pipes in your floor are your mufflers. I just want you to hear me fire mine up at Gainesville Marina!
You might try emailing nautiquefanatic. He has some of everything over at his place. |
