ok, I take the boat for a quick hot lap after I change the oil at the local lake and I find myself with 2 jet ski sherrifs following me for over 1/2 hr at 55+ mph. It seams that they came after me right after I got on plane and didn't even know they were behind me until I came back to the marina to load up the boat on the trailer. No ticket but a warning to get mufflers next time out or I will be cited. So, any suggestions on mufflers that can bolt to cast alluminum tail pipes or do I have to remove the tips from the transom and replace with complete mufflers... I heard good results from GGB and Gibson...I have twin n/a 502 mags with Imco manifolds.

Suggestions Please...thanks

I would recommmend GGB extremes. It is hard to tell from your picture, but your tips may be a bit too short to clamp them on. I think they need a minimum of 3" to clamp properly.

A buddy just installed the Gibsons on his blown Cig. Really quieted it down. No noticeable performance change.

Thanks all;

Fred, thanks for the offer, I will give you a ring to check on my options-

friend has both the gibsons and ggb on both his laveys....loves both but the finish is sure nicer on the ggbs and the gibsons are much cheaper...I guess you get what you pay for

GGB's are 316 SS.
Gibson's are 304 SS.

ah ha! thats why side by side there is a very noticable difference; the density and depth shines through ...GGB for me

I just put GGBs on my Gun with 850 blower motors, it is quiet.
You can talk now until the wind gets you, it's like a set of small blocks compared to before, know more ears ringing, they really did work for us!
