I have a y pipe that might work for you, what exactly are you looking for?
I have this pipe which you could probably modify. http://www.ebay.com/itm/NOS-marine-muffler-XT-TPD-3504-Centek-Industries-1200442-surge-tube-3-/121693132400?hash=item1c5579d670&vxp=mtr |

Well guys this got much discussion as I hoped it would.. I built the y-pipe to see if it would work.. which it did.. will it work without failure?? Probably not! So I've come to the conclusion the added sound and unknowns is just not worth it using this method.. And the PVC has kinda a weird exhaust note .. So the Hull hugger muffler goes back on until I decide to purchase a Centek y-pipe in the future.."

Great idea if you are only looking for a test method. NOT a permanent solution. The pvc will fail and boat will sink. The resins used on the exhaust components are different, if you try to patch one of those using standard boat resin, it will not hold together over time. I agree with the idea of if you like how it sounds, spend the money and get the proper setup to avoid a catastrophe. My $.02

I respectfully withdraw my earlier suggestion. Got curious & looked this up on US composite site:
9. Do you sell high-temperature epoxy? No. Our marine and commercial use epoxy systems can only withstand temperatures from 150 to 195 degrees. Most high-temperature epoxies on the market will require autoclave or oven cure cycles. |

Joel, You can NOT compare a thermoset to a thermoplastic. They are two completely different types of non metalics. Go back to your BMW!! It was not heat that busted up your hull hugger. Vibration and a cheap build/poor engineering if you ask me. |

How much more resistant to heat are the fiberglass/epoxy components such as the hull hugger muffler, Invertaflo muffler, or in the case of the hull hugger, the fiberglass sections that go from the riser to the muffler? I've already had to replace one of those due to overtightening and probably heat from the PO years ago.

His pipes are 3.5 in and 4 out. He needs a [4"] plug as Tony mentioned.

Was just something I read once, but it seems plausible in theory. A tennis ball diameter is 2.7 inches, not sure what exhaust tip inside diameter is exactly, maybe wrap in a rag first. Anything would be worth a try to not go down without a fight.
Mine has a transom ladder and no platform so they'd be easy to get to, not sure I'd wanna try it with a platform boat |

I made a cover frame out of PVC pipe for my Jet Jon. Not only did the material distort badly in summer sun, some of the properly primed & glued joints let go.
Don't know if it is economical, but you could wrap the PVC in epoxy resin-ed glass, then it would be safe. Put in hose clamp bumps while you are at it. |

this isn't the place I'd try to save a buck -- and usually when I can save a buck, I would. If you're purely removing the muffler, you'd need what, 3' per side of 3" copper? ~$200 total? so why try to save $150 on something below the waterline. my $.02

That won't keep the boat from sinking

Keep 2 tennis balls in the boat,. In the event of an emergency they can be stuffed into the exhaust ends.

meh. the late eighties budget centurians came with PVC pipes from the factory and are still going.after 25+ years. They are the dull ones with the fiberglass engine cover with a tiny apolstered pad on top of it.
Agreed, offshore, not even a consideration. I just don't buy most the doom and gloom. They sound like blue man group on meth, don't like the sound one bit |

EXACTLY!!!!! And this is designed to withstand that heat for short periods of time. Wait till you overheat the s**t out of that PVC. You won't have delaminated hose that simply needs replacing. You'll have a three inch hole directly thru the hull after the PVC has completely melted away. This is no different than somebody putting an automotive rated carb, dizzy, alternator, starter or fuel pump on their boat. Sure, it'll probably work fine maybe for as long as you own the boat, but all it takes is that "one time" when it goes boom and your boat is up in flames or sunk and people can potentially die all in the name of saving money. By all means let us know how that works out for you when that "one time" does happen. |

I'm no plumber but i have built some pretty good potato cannons. and some not so good.
But knowing what the pvc looks like after a good range day I would have to say i wouldn't trust any bit of it below the water line on my boats. especially with the exhaust gasses which are extremely corrosive. i wonder what it would do to the pvc. also do you have any idea how quickly you will be swimming with the fishes with a 3" hole under the waterline of a boat that small? I just finished safety drill training at my local coast guard base which covered this specifically. And just to give a little perspective, an open exhaust pipe below water line left unnoticed can leak roughly 150-200 Gallons per MINUTE, becoming exponentially more as the hole gets deeper in the water. So play on the safe side and if you are going to be a test hamster than bring a hammer and some exhaust size wooden plugs if you don't already have some in your ditch bag. Because time to get towed in may be too long. -Tony |

Your OCD is flawed. You still have the alignment marks on at the joints! Peter, I'm not aware of any ruling about having to use the purple primer in this area but, it sure is a good one. The other big problem with primer is not using it at all (typ. on DWV with plumbers cutting corners) or letting it dry before applying the solvent cement. I'm proud to say that after running close to 2000 feet of sch 80 10" and down to 3" and then hydro'd to 250 psi we didn't have one joint push apart. BTW, we have been back up and running for over 6 weeks now after the repair. |

And you won't see the primer I used past the fittings Pete because I measured how far to apply it on the pipe/fitting so it wouldn't show.. my OCD kicked in |
