WestEndAngler did a whole thread on this Marshmellow Exhaust...

IMO - the exhaust only adds more noise but not much performance - but
if done with some carb changes will help get more from the carb,,,

When mine rusts too much - I'm going with the quieter SS stock one
from GD made for my 35 GDSD...

Take a look at this one:

Thanks

My MM is quieter than my stock exhaust.

have you had any expeirience with th gecker muffler

Sounded "nasty". Is that in a good way, or bad? I've heard the crossover and liked the sound, just mainly wondering how the gecker sounds. Hard to tell from the videos posted.

Here is the Gecker Exhaust viewtopic.php?f=2&t=5006
some pics and video.

Hope that helps.

I have a Gecker exhaust on a pro drive, and I have been very happy with it. Gecker's muffler does not just sound good it helped my bottom end dramatically. I have never run the Marsh Mellow, but I have heard good things about it.

Used my sound meter to get some readings from the stock and MarshMellow pipes to see what the difference was. All readings on the trailer and +/- 1db as the meter I have is not digital but accurate.

5' from exhaust tip / straight on

stock-78db @ 1000 rpms
MM-79db @ 1000 rpms

Stock-98db @ 4250 rpms
MM-98db @ 4250 rpms



3' from exhaust at seat/pod in boat

stock-83db @ 1000 rpms
MM-82db @ 1000 rpms

stock-100db @ 4250 rpms
MM-100db @ 4250 rpms

I kinda expected the MM to be a little quieter from inside the boat as the tip shoots straight back but it wasn't the case. However it shows that the MM has basically the same noise level as a stock pipe even though to the ear its seems quieter. And is much quieter than the Hopkins I had on it. Anything above 85db is considered damaging.

Don't know but it is louder.

Thanks for readings Poker1

i know WEA's MARSHMELLOW muffler wasnt near as loud as my single crossover

Thanks for the information posted about the MM exhaust. It backs up my testing results. I found that the readings from the drivers seat are more motor noise than exhaust noise. I made this monstrosity to get engine noise levels.

what tha f*ck?!!!

That is six feet of ceramic fiber sound deadening. It was a collection of experimental exhausts that I haven't perfected yet. Very quiet quiet but completely impractical.

Glider, thought it was a super quiet exhaust for the longtail guys.

Whatever exhaust you get I would not go with anything else except stainless for salt water. I had a regular GD exhaust on my GD35 and it rusted to crap. Now it was five years old and ran in nothing but salt water four of five times a week during the season, but i cleaned it every time and sprayed it down with corrosion-x.
My advice would go stainless on everything, even bolts and washers. And i had a very hard time getting my old exhaust off and broke a couple bolt and had to re-tap the hole. Now after about every two to three uses i am loosening the bolts and tightening them back in to be sure they don't seize up.
I also used never seize and haven't had a problem yet

I would like to see the dB meter behind my hopkins
