I am in the process of redoing my bilge area and have everything out of the boat, so if I was to switch my exhaust to run external mufflers, now would be the time to do it.

I am running 800 horsepower and currently have the 4 1/2" Eddie Marine exhaust with the switchable mufflers built in.

We all spend so much money to make our boats LOUD and ok perform too, but look at all the threads "loudest boat you've ever heard" not "quietest boats you've heard".

To conform to these wonderful California sound laws, I am thinking running the external mufflers. I understand that at some launch ramps they are doing visual inspections (some old farts are usually doing them) as well as a Db test with a meter.

Any idea on mufflers that will work with this horsepower?

I am in the process of changing to external clamp-on GGB Extremes. Everything I have heard suggests these are the best out there right now.

I would take a look at the GGB's. I am sure there are others but the GGB's were my choice. With all the talk of noise restrictions, it was time to quiet things down before I received the proverbial ticket.
I am running a 540 with Keith Eickert exhaust. I stll get a nice rumble but without the crack of an unmuffled exhaust.

I posted a similar thread in the Formula forum. I am also looking for a muffler to replace the Silent Thunder Platform.

I am not as concerned to being legal but I do not want to be too LOUD either. Any recommendations for a good sound without robbing HP's from a HP525?

Who sells the GGB's?

Thanks,

Jamal

Exactly... Everyone says GGB's but who sells them and what is a good price?

Nothing coming up on a yahoo search, except OSO forums and Trick doesn't have them on their website.

Call Fred at Trick. He may be able to hook you up.
Also, ONeil Performance on this site( see his banners) has them listed.
Last week I saw some clip-on GGB's on e-bay.
I have a set and am very pleased.

fred also has the new cmi's they may be quieter the anything on the market right now

Has anyone tried the Livorsi Marine's Muffler Insert's?

They are advertised as lowering the decibel level by 5 to 6 and is that enough to make a thru hull exhaust not to be considered LOUD?

I am looking for a rich sounding note without sounding abnoxious or having to be legal?

I have 2 pair of GGB's 4 1/2" clamp on style for sale if your are interested.

Also, have 2 pair of CMI's 4 1/2" clamp on style with air pump.

Call Rick 847-874-2035.

We have GGB's in stock. Inserts, clamp-on or transom mount. We run them on most of our customers boats and have found them to be the best performers. The biggest complaint is that they are too quiet at idle.
