PVC y pipe gt40 muffler delete

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.

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.."

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.

uhm i was being sarcastic   ha ha

what does stfu stand for?

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

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.    

That won't keep the boat from sinking

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

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.

Lmao! You got me on that one Pete!

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

By the way this is what the inside of a exhaust hose looks like after someone overheats the *************** out of there motor
