Are any of you guys running the new CMI Sound Elimination System mufflers? If so did they bring your decibel levels down alot? I got stopped yesterday and am at 101.5 and need to be at 90 or below. I can't use the down tubes from CMI because of my staggered setup. Thanks, Steve.

Hey Steve, I am using the Livorsi E-series mufflers and they seem 2 do a good job! Tracy

I put the north stars on my boat, they should get you down to 90 without a problem

Got my ticket for 114db !! No mufflers......

This is what scares me.

I also could use a set not because I am getting stopped but after I shut it down in marinas I get the applause.
Running at 45oo for a hour gives me a ring in the ears also.
I am afraid that the mufflers that are effective bringing down the decibels below 90 will not support Hp levels in the 1100
plus area.

Check out the set of 4, that I have advertised in the "other parts and acc." section, ad #63, today. I can make them "clamp-on" or bolt on, I have all the parts and equip. to do it either way. Any size inlet that you need.
I'm open to reasonable offers.

I'll checkout the add, thanks. If I had a side by side motor setup, it would be easy. Wes 114 is up there, thanks for the info, Steve.

I run GGB's on 750HP NA and they are very quite with NO LOSS of PERFORMANCE. I think Lofty on the board is THE US distributor. Joe Murray

I have GGB's with Keith Eickert headers and was 94db at idle.

I had to add "downtubes" to pass our 86db noise law.

Isn't GGB out of buisness

What is your HP and what size exhaust. We can certainly check with similar set ups of customers that have successfully lowered the DB to pass and let you know if it will work.

Let me know are they NA engines or Blown too.

Hopefully we can help.
