Gary,
What's wrong with the old ones? You can repair them!! BTW, most here will remove them and replace with SS, copper, fiberglass tube or exhaust hose. ------------- /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 < |

I used sch 80 PVC in mine (as was recommended by SWCC at the time), and couldn't be happier. ------------- 1981 Ski Nautique 2000 SAN Looking for a 2000-2006 SAN |

Larry, Sorry I didn't mention the PVC option in my choices of muffler replacement. It's not #1 on my list since I'm still concerned about the heat even though you used scd. 80. I've run plenty of the 80 in the plant up to 12" and we have had issues with it. It works good until you get up into the higher temps. It's the return lines (150 *F) and above where we see the problems. The exhaust temp of a typical DD runs better than that temp!! Of course, you will not see the pressures we do!!! Still. PVC even though it"s scd. 80, I do not recommend it. Yes, I feel that the boys over at White Lake are smoking something in that back room at times!!!!  
One thing for fact, is I do know that their numbers are are all off as far as who the oldest CC dealership is!!! THEY ARE NOT!!!!!!  ------------- /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 < |

If you decide to replace with stainless or copper tubing, check your local salvage yard, sometimes you can find a real treasure.
I have about 8' of the 3" stainless from one local yard and paid all of about 12 dollars. Im not sure what mill it is, but it is thick enough to stand on. Mike ------------- Lakedog55 |

I've grown to dislike the tone of pvc because the base budget centurians were shipped that way, pains to hear a nice boat sound like that,
Muffler, copper, or all hose, sound better than pvc. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

ya i know u can repair them, i did that already a few years ago. the original ones are seamed in the middle and cracked..again. so im taking on water..so i thought id finally break down and buy new mufflers..
i talked to correct craft and they said the Verna mufflers are fine and they have been installing them for a while now. i just didnt know if there was any advantage to go with stainless or whatever..like maybe a power difference or something...if you go with straight pipes..instead of a muffler..or is it better to go with stock mufflers..i pretty much have straight pipes now because i know my old muffers are blown thru and dont have any baffles, they are the original ones...i guess 25 years on a set of mufflers isnt to bad..ha anyway, thats about it...thanks Gary ------------- let me know, thanks. |

Gary,
Go with straight pipe!! You are already used to the sound since you've mentioned the baffles are blown out of the old mufflers. They really only knocked off I believe around 10 Dba anyway. Yes, Copper is #1 on my list!! I just mentioned it in another thread that it does have the best tone. ------------- /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 < |

This is just a question but has anyone tried aluminium tubing?

Only if it's been anodized. Try to find it in shorter lengths and I feel you will have a problem. What'd the deal? are you trying to go extremely CHEAP??? I feel you are making a big mistake if you are going un anodized aluminum. ------------- /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 < |

It was just a question. I already have 8' of 3" stainless. And yes I did pick it up at a salvage yard. I was wondering if I should take it and have it flared. Or what would be the proper way to install to prevent leaks?
One thing I have figured out at this point of the restore whatever you think it can be done for in dollars and some cents add a lot more. ------------- Lakedog55 |

Don't flair them,put them on with double clamps and stagger the screw part like these-

Mike, Sorry i totally missed your response and, all day!! 
I'm glad to here you found some SS tubing and didn't go with the aluminum. Gary is correct that you do not want to flare the ends. You'd never get the exhaust hose on!! Did the salvage yard have any idea of what the SS type was? Many have even used carbon steal tubing but it it's last on my list. If SS, I always recommend 300 series and not the 400 "muffler" grade. ------------- /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 < |

| Would a 3/16" wall Dorque Pipe cut in half work for exhaust? |
Posted By: 8122pbrainard
Date Posted: August-13-2011 at 1:35am
I'm absolutely sure it would as long as the Dorque putting it in is ether you or myself!! The only problem is the special fittings needed. They aren't available like they were years back.
Al, Just to make sure, post the specs on the Dorque and I'll run it through the engineering. ------------- /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 < |

Hey I will bite. What the heck is a dorque pipe and which way do you cut so that is exactly in half?

Well, I didn't get a spec sheet or an instuction manual.
But I do have a photograph.

Nice pipe, very clean, By the way what year boat is that in the back,. After rebuilding my 86 I have found a new hobby, I want to rebuild a classic but not sure which year or model is considered to be "the classic"
Unlike a 69 camaro or 67 mustang The classic year on the boat has me guessing Is there a site with a bunch of models and pictures besides this one of course. Mike ------------- Lakedog55 |

Mike,
The "Classic" class is any boat built between 1943 and 1975 inclusive. I don't know of another site where you could see more CC's than CCfan. Other boats yes but you sure don't want anything besides a CC!! ------------- /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 < |
