Muffler Exploded

[jstenger]

Has anyone seen this happen before?

This happened on my 24 year old ski boat over the weekend. I ran the blower a few minutes before I tried to start the engine. As soon as it cranked over and fired, KABOOM!!! Luckily no one was hurt. I cannot find any info as to why. I believe there was probably gas fumes in the exhaust that ignited, and the blower only removes external fumes.

I am unable to find a replacement. Silent Rider is out of business. Sent an email to Larry at FAE for a custom muffler quote. Still waiting on his answer.

Why not clean it up and fibreglass patch it? You may also want to find the reason why there was a detonation, or was it some 24 year random malibu event?

I thought about fixing it, but there is so much more room to service the tranny with it gone. Couldn't find any info on the web about it exploding. Only things popping up were cars and trucks. No definite answers. Possible valve stuck open when spark plug ignited.

Wow that's crazy. Would definitely concern me as to why It would do such a thing. But fix should be pretty straightforward to re-glass or custom options depending on price. Did it make ya jump?

[jstenger]

Not me, but before I could look back to see what happened, my wife and boys were already out of the boat and on the dock.

I enjoy my FAE solution, straight piped. Since the outlet is underwater the interior sound is not much different than stock.

So I want to make sure we are thinking the same. Did you just add straight pipes, or did you add straight pipes plus the FAE tailpipe?

There's an argument that straight pipes + FAE will be quieter b/c all the noise gets put in the water. I cooked my muffler last summer and learned of that option only aft I paid for a new OEM muffler... you can get Stainless pipes in various bends from Summit/JEGS, etc.

Put straight pipes on there, I'm sure everyone on the lake will love it.. Not..

I have heard that straight pipes with FAE is actually quieter. Have not heard or seen a boat with this yet though.

I already had the FAE and my fiberglass mufflers started leaking.
I will link the YT video of it running on the trailer.
IMO wet headers are pretty reasonable and this is nowhere near that loud.
It has a very nice sound.

FAE thinks it's quieter:

First off, here is the original pic, since I was previously using Photobucket and it no longer shows.

Secondly, I finally got my pipes from Larry.

Pipes look and sound great. He was able to add baffles in the straight section to really knock the sound down. Funny thing is that it is a hair louder in the boat, but quiet from behind. Stood at the dock as my son drove away, and it was very stock if not quieter sounding.

Thanks for the follow up. For us with older boats, fabrication is the only way to go.

Its most likely louder in the boat due to the resonation off the metal tubes compared to the fibreglass
