I Keep getting tickets i have mufflers but still to loud but barley. any way or tricks to cut another 2 decibels with out getting 4 new mufflers??????

Are you dry or wet ? What do have in use now for mufflers ? What diameter pipes/outlet ? What size engines + hp ? Do you have a picture of back of boat ?

You could possibly install another muffler insert. It depends on what you have now.

i have a 30 ft eliminator daytona with twin merc 525. wet i think they are 4 inch not sure the brand of muffler boats in storage.

I need a tire for my car.. what kind of car you have... i don`t know, I think it`s silver.

LOL ^^^^^^^^...............pretty soon the engines wont be able to breath

I use the GGB inserts (4" dia and 5.5" long, 'performance' model insert which means slightly larger internal ring diameter).....They dropped my exhaust noise by 6 dB at idle using but this was on a warmed over small block. I've found them to be non-restrictive compared to some other inserts I've used.

E78-14. They are best for you!

I use Aqua Power Ltd. quiet, nice sound. And don't rob any horse power, accually helped the mid range torque

Nice set of boobies there 👍👍 icdeppl
