BY U BOY, Thanks, I thought maybe you were going to scan it and send it in an e-mail. I'll try and dig it up through someone locally, thanks for the offer! Steve

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.

My boat has Stellings headers with short dry tailpipes. I've heard of issues with the CMI's backing up water, anybody have this experience? BTW, my motors are 750hp naturaly aspirated.

Tazz,
I had the CMI's and did not notice any water issue. However, I could not meet the noise police requirements with them. The best I saw as 94db, I have NA 750's.
Hustlethis,
What noise level did you measure between the IMCO Gatlins and the Gibson's? What engine(s) do you have.
