suggestions for mufflers
 

anyone have suggestions for what type of mufflers to use on a 38tg? Dont want to get thrown out of my neighborhood. Needs to be set up for approx 1000 hp.

whats with the curved ones on the boat at the miami show.

HPI,s

donkey d!cks

Dry pipes with no mufflers, screw them all :)

Seriously, I think I'd spring for an on/off muffler system.

CMIs they really work well

I have a set of 4.5" donkey dongs that I will sell you. Put them on my TG last year and ran them for about 20 hours. Decided that loud is better!! :D:cool-smiley-011::evilb:

Let me know, I'll make you a hell of a deal if you can use them.

I have these ...but I don't know model/brand ...

But I'd like to add the rubber thing @ the end to prevent inlet water ...it's possible ??

Thant's what I run and the cops like it here.

Just for the record, NJ requires mufflers and requires that they be non by passable. Not like any of us bend the rules a little......Technically the switchable exhausts, aftermarket or from the factory like the ones used by Formula and Fountain, are not legal to use under NJ laws.

Do those effect performance at all?

Same in NYS - not sure I understand the reasoning...

We can get you in CMI's for the best price.

It's possible to add these rubber things at the end of the mufflers on mines ??
How are they called and where I've to look for ?

The rubber flaps clamp on very easily.

They are called "flappers" and there are many different types available; they are simple to install they just attach with a stainless steel hose clamp on the outside of the muffler.

I took mine off as the rubber ones tend to tear high speeds. I think not having a swim platform contributes to this as the flapper can stand straight up. I have been told to stuff a nerf ball (or a towel) in the mufflers when rafting up to keep the water out.

where can I buy ?
Model type / size ??
I can't find @ Overtons or similar..

No

Measure the outside diameter of the tailpipe. It'll probably be 4", or 4.5". That's the size you'll need. Try lookin at Eddie Marine, or maybe Teagues catalogue. Usually anyone that sells exhausts will carry the flappers. All you need to know is the outside diameter of the pipes, and you're set.

There are several styles available here:

exactly, I just put up with mine, even though I have threats made to me and a bunch of angry mob waiting to kill me every time.

I went with the gaffrig switchables

Go with the old style old style switchable CMI you will be verry happy! good luck, Greg

Mine are CMI , and I have a switch that I can close them but I thought it was for noise reduction

Today I recieved an email from the ex owner of my boat :

Hi Michele,
you have the flaps inside the mufflers and you want to add flaps on the outside ?
I think, its to much backpressure for the engines, they will runing to hot and will not have the full power !!!
Dont do this, the mufflers are enough !!!
as you can see on the picture you sended me, the flaps are fixed on an exhaust pipe and not on a muffler !
Belive me, flaps and mufflers are to much for the engines.Try to go full thottle with the mufflers closed, you will loose about 300 RPM and the engines are running to hot.
Greetings
Kurt

What do You think ?? Is he right ??
The only thing..it's I'm a little bit scared from the waves that we have in our seas....and the risers are not so high .....



Mike

I had the internal muffler flaps on a 96 Topun and they let water in to ruin a motor. Mercury as well as TNT told me that the outer rubber flappers are the way to go to play it safe.

I've bought 4 @ Phil yesterday ! :D

Kurt is right....you don't want to run the CMI switchables in the closed position at high rpms....once you are going to idle or float awhile you can close them....
