It's soon time to buy some exhaust mufflers with all of the noise restrictions. So who makes the best? Most of them only reduce the noise levels around 10 Decibels. I'm running a 600hp.

BBB,
Do you have the Gibson Power Curves? I just got off the phone with Dana Marine and they are sending me their "Sample" Power Curve to test fit on my Nordic! What a cool idea!
Should be here by Wed.

I'll sell you a set og Gibsons for $800.00 for the pair (2 sets) they have been used a few times only.

Hmmm, I'm seeing a whole lot of Gibsons for sale or in the dumpster. I've pulled a few sets off lately.
Try the GGB's, they actually "work" without robbing all that expensive HP.

I have special pricing on the GGB's for OSO members.

Definatly go with the GGb's no loss of horsepower, but will bring you down at least 10 db's
