Yes they are.....
The Gibson Bullet Marine Silencers have proven to reduce decibel ranges within and to surpass the 88 db limits required by the California SAE J2005 Motorboat Sound Law without compromising power. The Gibson Bullet mufflers are manufactured from highly polished T-304 stainless steel and are designed with Gibson’s patented clamp-less system for hassle free installation. Power Tip Marine Mufflers are also available with OE style thru-transom mounts to provide the factory look without the factory sound.
For real world DB numbers on some of the competitors, I have the DNR record from tests conducted on Lake George N.Y. in October.
The Gibson Bullets Feature the Following:Ease of installation.
Tested up to 1,200 HP with minimal or no power loss.
High quality Stainless Steel construction.
OEM style transom mount.
Straight through design.
Utilizes water to dampen sound.
Has been designed and flow tested to ensure maximum flow.
These silencers were specifically designed for large displacement motors such as 500HP, 502, 525, 525SC, 575. and up to 1,200hp. Gibson is in constant contact with all major Performance boat builders.
Priced sensibly! Dare to Compare.

Re: Best clamp on mufflers
CMI Sound Elimination Muffers reduce sound emissions to levels as low as 85 dB. The mufflers are engineered to reduce sound without restricting the exhaust or creating unwanted backressure, which can inhibit the engine from reaching peak power. A superior design using T-304 stainless steel results in fewer parts than competitive models.
Besides being designed and built by the industry leader, these mufflers look great, provide a nice muffled sound at idle and open full for high performance operation.
OE thru-transom mount and clamp on styles in stock now for immediate delivery. Free shipping until January 1, 2007.
We will beat any competitors price.

they do not meet current db limits of 89. These test were
conducted by me personally and the Lake George park commision marine patrol. 2 boats had 525'S and one has
500 mpi's. Both came in at 90-91.5 DB,s. Nice system but
the regulations are very strick in my neck of the woods.
.01 over 89 and you get a ticket.
