MUFFLERS...are you using them or not?
 

I was wondering what people are doing about the noise restrictions on our waterways these days. I am curious to see what boat you have, engines, HP, and where you boat, etc...

I am serious about this...I have a friend that had his weekend ruined last weekend at Havasu because his boat wouldn't pass the decible meter test and he wasn't able to go boating :mad:

Please answer the following questions...
Boat
Engine(s)
Horsepower
Mufflers you are using (if any/ do you like them?)

Here's my info

1997 33' Powerplay
2 HP500's
525HP (rebuilt motors)
Using Zoomers Marine mufflers....I love them!!!
I boat in the Pacific coastal waters and mostly Lake Havasu City, AZ.

Thanks OSO :D

Re: MUFFLERS...are you using them or not?
 

I run GGB extremes on dry CMI headers and tails on my 540. They sound great and have no power loss.

Re: MUFFLERS...are you using them or not?
 

89' 311 SR1, basic 454 mags, Eddie Marine Thunder aluminum exhaust. Removed silent thunder box and installed new Stainless Marine tips with "superflapper. All parts courtesy Trick Marine (shameless plug :D)


We don't have (fortunately) noise issues here, just the manatee issues.

Very seldom see an "offshore" or "performance" boat with mufflers here.

Re: MUFFLERS...are you using them or not?
 

Not required, but I run GGB's by choice. Like Checkmate 454mag, my 540 is a little on the loud side.

I am also very happy with GGB and Trick Marine - excellent service in the getting them ordered and delivered.

Re: MUFFLERS...are you using them or not?
 

22' Donzi Criterion. 502 BBC. Probably around 550 hp. No mufflers. In NJ, you are required to have some kind of muffling device, or u get a tkt. I take it easy around the marine police, and havent been bothered yet. That sound you hear is me knocking on wood.......

Re: MUFFLERS...are you using them or not?
 

Have to because of state laws
however, I am not totally compliant because they are switchable :)
1999 Advantage 28' Sportcat with Twin stock 502's
Running the Teague 450's and LOVE THEM.
They really take the bark out, both open and closed.
Closed you can sit in the back seat and carry on a conversation.
Open, you can too, just talk a little louder but still able to :)

Re: MUFFLERS...are you using them or not?
 

43 Black Thunder, TMP 750 HP, normally aspirated, CMI headers, CMI tails, wet @ the end with GGB Extream muffler tips. Much better than 4 1/2" Stainless marine Gen III thru transom dry until last inch. You can talk in normal tones until wind noise gets too loud. Joe Murray

Re: MUFFLERS...are you using them or not?
 

28' Nordic with Whipplecharged 540/800HP running GGB mufflers. Mufflers are not required here, but I like a boat to sound good, but not incredibly loud. These seem to be just about right.

Re: MUFFLERS...are you using them or not?
 

We have a Top Gun ts, Pfaff engines, Stellings, bought Gibsons clamp ons...they work great...use them at Lake Mead or Havasu...take them off for the coast runs

Re: MUFFLERS...are you using them or not?
 

Yes, GGB Extremes.

The only way to fly!

Re: MUFFLERS...are you using them or not?
 

35 fountain
575's steped on to 690 hp ish ea
cmi / wet but its not loud just sounds GOOD :D :D :D
its supposed to be loud,, i wanted a thunder boat.. :eek:
No mufflers :evilb:
according to the law i guess i am not legal,,, will see ,,, i bought it this way and it came new this way.. :cool:
next they are going to say my viper is too loud or my wifes 745 or well i guess they did tell me my cannondale dirt bike is to loud and i paid it, doh
my harley is really loud no issue there ??? hmmmm this chit dont make sense,., bunch of tree huggers pushin politians around or something.. its bs though....
I have a great idea lets all instead of this muff bs buy ear plugs for the dick heads... whats next u cant wear a blue lifejacket ? or have black stries on the boat.. its all bs revenue for the state and a reason for them to puill u over..
they should be pullin over the dopes on jetskis and the newbie dopes that just signed up for a boat with 0 experience,, the guy with a go fast has generally had some seat time and has a clue,, that does not apply for the majority of what i seee out thiere on in other crafts.
ok thats my o2
anyway no muffs here.
for now anywway

Re: MUFFLERS...are you using them or not?
 

I purchased some HPI clamp-ons but I have never used them. I boated in Tahoe three weeks ago and just idled in on one motor and tried to be quiet around the docks. Pfaff 1000's, with Stelling big tube headers. My Jag is pretty quiet isn't it Lofty, You heard it on the Sacramento river, Bridge to bridge. Doug

Re: MUFFLERS...are you using them or not?
 

We don't need no stinkin' mufflers!!!!! :D :D

Top Gun
1200HP X 2
Stellings Dry Pipes

I'm planning on rattling windows in the Wash. DC area next weekend :evilb: :evilb:

Re: MUFFLERS...are you using them or not?
 

We're not required to use them, but it's very annoying to have some one come blasting thru at 2:00 AM without mufflers.
Don't get me wrong, I love the sound of open exhaust and usually run like that offshore: just not in heavy populated areas. Besides, I think it's cool to have a relatively fast boat that is also quiet. Dave Scott/Barcardi has the right idea.

Re: MUFFLERS...are you using them or not?
 

Have tested 20 sets of mufflers on dry and wet exhaust on 850-1150hp blower motors. There was no muffler that met the j-2005 regulations of 90 dbs. We even put up to 3 mufflers on the 1150's- 2 inserts and a clamp on, still only got it to 94dbs, with a total 42" of mufflers. The Turn downs work for the stationary test if you get them to clear drives and tie bar which is hard on Merc 6's.On the moving test the technology is not there yet . I have tested ggb's hpi's gibson, cmi, stellings.I believe the answer on big hp is a turn down inside the transom and exit below water level. have spoke with several racing teams and manufacturers and they agree.

25' Active Thunder
Merc 420
GGB High Flow Louver tips

Don't have to have them but with my two young girls, it is easier on their ears. They work great and no loss of performance.

around 500 HP
CMI Elbow w/wet tails

Haven't had a problem yet here in upstate NY. Knock on wood! She is pretty loud. The laws here are not clear on weather you can modify your exhaust such as silent choice or put custom systems on. It seems even some law enforcement are not clear either. I have heard of people getting noise tickets and when they go before the Judge the judge throws the ticket out depending on the circumstances.

Re: MUFFLERS...are you using them or not?
 

So far we don't need them in Mississippi, Louisiana :D

We will see when we go to Emerald Beach poker run, but I think there not enforcing it there either.

But I can see it coming and will have to get them soon or later.When it first bust off with no water its loud.In thr boat the blower whine is louder that the exhaust :evilb:


2001 388 Hustler
It has the CMI's with wet tips stock.
500 efi Whipple 3.3 4.5 pulley 779hp
. 4.0 pulley 867hp

I think the DP is close to a stock 500efi at Idle only

Mufflers are going to suck :mad: :mad:

Re: MUFFLERS...are you using them or not?
 

I have IMCO gatlin mufflers on my 2005 HP525EFI's. I would rather not have any mufflers, but I got them because of the law. I have no idea what dB I am at with these mufflers.

Re: MUFFLERS...are you using them or not?
 

Thanks for the info guys.....keep the info coming!! :D

Re: MUFFLERS...are you using them or not?
 

944 hp blown 540 single,stainless marine offshore 3's w/5 inch tails,even with wet tails was rudely loud,bought ggb's from Lofty (great guy),seems quieter than was with lightnings,haven't tested at w/o throttle yet(will do back to back at hardy pond before summers over hopefully),Smitty

Re: MUFFLERS...are you using them or not?
 

Glad to hear those things worked out for you Smitty! Now if I could just get my own boat in the water.

Re: MUFFLERS...are you using them or not?
 

Formula Silent Thunder...nice mellow rumble but will still pass DB tests.
I do like loud though :rolleyes:

Re: MUFFLERS...are you using them or not?
 

22Baja
350
400ish
nope.. none here

Re: MUFFLERS...are you using them or not?
 

29 Outlaw, 496 Mag HO's. Was 97db at idle without mufflers, got ticket :( Now running GGB Extremes. Sounds good, no more problems....

Sucks having to run them tho, it sounded GREAT without them.....

Re: MUFFLERS...are you using them or not?
 

Yes...I have in-line GGBs on my twin stock 496HOs and did not experience any loss of speed. The boat is much quieter, but still has a great sound.

Re: MUFFLERS...are you using them or not?
 

I have GGB's because of the law. Not sure of the decible level yet. 2006 Dragon 39.

Re: MUFFLERS...are you using them or not?
 

30ft Scarab
502X2
No mufflers yet
It doesnt seem fair...if you have a motorcycle...the louder the better!

Re: MUFFLERS...are you using them or not?
 

I had to install mufflers to met new federal laws. The boat was already quiet enough at idle because the pipes turn down inside the transom and exit just below the waterline, just where the water enters the pipes anyway. It sounds like an old mahogany runabout idleing along but gets it voice back once on plane and the exhaust clears the water. Slightly modded hp500efi in an eliminator daytona.

Re: MUFFLERS...are you using them or not?
 

hay guys, you got any links to these sites????

Re: MUFFLERS...are you using them or not?
 

Jonas, We will be coming your way for the BCPR in a coule of weeks...are they enforcing noise laws up on the Delta??

KL

Re: MUFFLERS...are you using them or not?
 

KL, it's hit and miss. Jonas will know better but I've been hearing mixed things. Don't worry about it for the Big Cat. How could they possibly stop 150+ boats? Just don't be a straggler and you'll be fine!

Re: MUFFLERS...are you using them or not?
 

If anyone is interested in saving some $$$, I have a set of GGB Extreme 4" clamp ons brand new in the box.
PM or email me.

Re: MUFFLERS...are you using them or not?
 

triple 551 c.i. 600 horse natural aspirated. cmi pipes. have external switchable muffler instaleld but never have used em. always liek to keep it loud :D

Re: MUFFLERS...are you using them or not?
 

No real mufflers but I use the silent choice (which I love) around locks and marinas religiously........I think by law your supposed to have a "muffling device" but Ive been beside several cop boats and they dont give me a hassle at all but Im always in quiet mode.......spoke to one cop about it he said......and I quote "personally Im ok with it" (open pipes) "but if the guys being a jackazz , like reving the hell out of it in a confined area, Im gonna do something about it"......sounds reasonable to me

Re: MUFFLERS...are you using them or not?
 

Keep them :rolleyes: They make my 25 Outlaw 2 mph's faster than your Tiger :D :evilb:

Re: MUFFLERS...are you using them or not?
 

20' Bayliner 1988 w/ twin Zul 1050s
Over transom dry exhaust - no mufflers

I never get stopped because the cops think the noise is coming from them "Cigar" boats all around me.




Sorry, Semper. This thread was too serious.
