pros a cons? Im getting mixed advice from local friends and boat guys. they also dont have a classic like i do. Im sure it would be weird if you put straight pipes on a 100k wake boat. but seriously who has done this and what are your thoughts? any cons? Thanks ------------- 1986sn 2001 |

1986 ski nautique new 351w block gt40 heads used primarily on lake houston/upper san jac river. but the wife and i have hauled it to canyon lake, summerville, and hope to pull it to Florida for the meet up. i live 10 mins from the lake. not on the water but we were out 3 out of 4 weeks a month in the summer. we didn't ski much last year because it was the first year we got to enjoy it since i started rebuilding stuff. i want to wake board behind it this year. ------------- 1986sn 2001 |

Keep in mind that for many of us, mufflers are "new" technology, as our boats were never equipped with mufflers in the first place...... The rumble of an unmuffled V8 can't be beat, and never "gets old".....  LPSL. ------------- 1974 Southwind 18 1975 Century Mark II |

+1 on what 74Wind said.... I think LPSL is the reason why my 72 saw more water time than the 88'. The sound is pure music to my ears and most people who are around as I approach a dock, ramp, raft up or slow down as I enter the no wake zone............. the first comment is usually......." Dude, I love that boat and that thing sounds freaking awesome!" "What year is it?"   ------------- "Morfoot; He can ski.

Andrew, I'm old, and all my boats are old. I've spent many an hour riding in and driving old boats. The sound does NOT get old!  It's my opinion that marine exhaust systems are less restrictive than stock automotive. Don't expect performance gains by removing the mufflers. I suggest removing them. You can always put them back in. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

We are in the process of re powering this Tique and have removed a perfectly good pair of mufflers and exchanged them with these copper pipes from another boat. It will probably be a little louder, but I don't think it will be too loud.

As much as I love open thru pipes this is the real question. I had no mufflers in the 81 and it was extremely loud and extremely cool. But after being in the boat for 5-6 hours worth of skiing everyone in the boat was deaf. The drone can be so deep at certain rpm's that is it just not comfortable. Go ahead and flame away but I have open exhaust in the Hurricane and love it but my ski boats are muffled. |

I heard that from another member recently. Our Malibu is the loudest of our boats by far. I must either be deaf or you guys have sensitive ears, as I've never noticed the boat to be loud for skiing, only for sitting in the back seat while cruising. |

Agree with Alan, drone sucks, but if you never spend a ton of time in it at once, then you can't beat the sound of un-muffled duals. ------------- Craig 67 SN 73 SN http://www.correctcraftfan.com/diaries/details.asp?ID=6103" rel="nofollow - 99 Sport 85SN |

The drone gets to me too like Alan says. My ears are always ringing anyway and after awhile it only makes it worse. I have just spent the good part of 2 weeks getting this one changed over. Originally Shamrock used 3" hose from the risers reduced to 2 1/2" water pipe and tips. A donor Nautique offered up the 3" mufflers and tips. Hi Teks round out the package. Splashing in a couple of hours,will report back on how it sounds. Disappointed on the fit of the Hi Teks,they certainly were not bolt on.   ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Bite Me Pete. I don't sit in my backyard that backs up to the lake using the boat for an intermittent 10 minute ski. We load it up and spend 5-6 hours in it. With the 81 I used a flyhigh so when pulling a wakeboarder I had people sitting in the backseat for sometimes 20 minutes The drone gets to everyone in the boat and can really start to test peoples patience. It makes people tired and cranky and shortens our day. So again, my hotrods are loud my ski boats are not. |

Would consider how many hours you run a year and what percent is while pulling someone. Loud is cool and sounds great but as many above have also stated, it will wear on ya. Best plan is get at least 2 boats, 1 loud & 1 not so loud!! ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1143" rel="nofollow - Mi Bowt |

So, if you don't have residents to piss off that could complain which may impact your boating experience (authorities) then it's just a matter of personal preference. Gary, I've noticed that exhaust and solid platforms don't get along so well. The at rest reverberating can be obnoxious IMO. |

| Alan nailed it. Love straight pipes on my hot rods, but have re-muffled all of my serious ski boats. It makes a big difference behind the boat at slalom speeds and above, especially barefoot. The neighbors complain less too. |

The day I can't handle straight pipes is the day I turn in my man card. I will say any dual pipe CC should be straight pipe. But a hard core slalom tug which would be anything NWZ and newer I'm not so sure I'm in a hurry to take the muff out, despite the repeated request from my wife. However I don't think I'd ever do a muffler repair either. ------------- Please support The Cystic Fibrosis Foundation 1976 Ski Nautique 351 Escort 1993 Ski Nautique purple and black 351 HO PCM |

Although this may not win me any friends among the majority of the crowd here... If you have people riding in the back seat a lot, and you go on longer jaunts than just taking a couple people skiing at a time, I vote for the mufflers...strongly. Even with the muffler, the exhaust drone from the back seat of our boat when on plane is kind of annoying until you're up above 25 mph. Until recently (we're relocating and going to live on a lake) we tend to run the boat for 2-4 hours at a time. If you're going to be out early in the mornings, I just consider it a courteous thing to do for others on the lake. ------------- 1996 Sport Nautique GT40/Acme 422 |

I'm sure Larry was a little tongue in cheek, but just to clarify... The above BFN has a bit more compression, a warmed up cam, aluminum manifolds and 4" straight pipes... So it is a bit louder than most other set ups being discussed. It is also why that boat now sports mufflers! The sound was great from the driver's seat, but less so from the back and not much fun when behind it. It was also quite unloved by the lake community.

I honestly wouldn't mind waking up and hearing a Correct Craft running around the lake, but hey that's just me. Not that many loud boats on my lake though. I imagine once I'm older and live on a lake, I'll have mufflers on most of my boats. ------------- 1972 Mustang |

Seems like there is a split decision on the matter. lol I think im going to reinstall the mufflers.... my favorite thing to do is just cruise around in my boat at 10-15 maybe slower and i do not want the wife complaining about the sound. She already complains about the storage costs! yes it would sound great and thats why i was thinking about straight pipes but i think it would be cool for about 1 weekend. I was planning on going by the boat on the way home today and measure everything out. does anyone have lengths of hose that i will need? ------------- 1986sn 2001 |

Smart move.. It will increase your time on the water in the long run. Hose length will depend on the mufflers used. Just measure up the old stuff ------------- 05' SV211 TE 73' Martinique had:96' SNOB had:76' Nautique had 77 Tique |

I have a 3.5 to 4" y-pipe on my boat.... Slow cruising without much weight in the boat its louuuuuud. WFO sounds awesome. 90 percent of the time it sounds like most other inboards. Not exactly quiet by todays modern boat standards but not obnoxious. Our lake doesn't have many houses on the the water at all (less than 10) and its a good sized lake with canyons. |

Why not build a baffle assembly to slide into the straight pipes and pin them in when you want it muffled a little?? Motor cycles and hot rods used them for years. Just don't restrict it to the point that water can't freely escape. Takes all of 1 minute to install. For sake of explanation it would resemble a piece of threaded rod (approx 24") with several square washers attached along it's length. They knock the harshness off without quieting alot..

Muffled is an important detail for sound control but cubic inches don't really factor in... Compression ratio, exhaust manifold material, cam timing, presence of metal in the exhaust track (vs hose), exhaust diameter... Those are all bigger drivers of volume. Some of the noisiest boats I've heard had itty bitty small blocks (283ci). 273-318 Chryslers also ring loud, as do 302 HM's. |

Well I tried it out today just drove it home about 6 miles from the launch not going over 3k. Sounds pretty much the same I guess. With out a meter I can't tell and it's been 10 months since I drove it last. Maybe with more seat time I'll notice a difference. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

| After 2 years of owning our 87 SN 2001 I have decided to dampen the noise. Kid's complain, wife complains and it honestly gets annoying after 3-4 hours on the water. My first thought was going to a hull hugger muffler but $600 is a bit steep. Started thinking about my baffles on my motorcycle and building an insert like Duane described. |

Guys, Well I went straight pipe. After the rebuild i had the dizzy out 180 and had a back fire. Obviously my fault should have checked everything closer and I fixed it. Boat runs great now. After the back fire I was tuning in the driveway and there was a bunch of water pooring in the bilge. Not normal. I took the floor section up and found my two stock fiberglass mufflers had exploded. Lol With a weekend ahead and not having my boat running for such a long time I found some extra exhaust hose in my storage and piped it straight out the back. I honestly like the sound. The wife says it's loud but eh. https://youtu.be/AQ3-z-ytBSc ------------- 1986sn 2001 |

I have run both on my boats. Never noticed a power advantage. Loved the open pipe sound, especially when you fire it at the dock and the gear heads all turn to see what you are running. Separately we did a lot of ski time when maybe it was not fully legal. Midnight runs come to mind. Full moon runs are incredible on glass you can only dream of. At these times the mufflers do a great job of cutting your noise exposure. Mufflers also allow conversation in the back of your boat. I see the positive in both and have enjoyed both but chose to stay with mufflers for now. Mark ------------- |
