As some of you know we have been battling the noise issue up here the past few seasons. I had been running Gaffrig switchables but they just didn't cut it.

After some research on here, (Troutly) I decided to try the GGB product. They are a full time muffler that doesn't choke the power and they did the trick!

I'm now 89.6 db and my neighbors will love me for it

If you are having noise issues I highly reccommend GGB. They ship the same day as you order them too!

It is NOT your neighbors that were complaining!!!! Now I am pissed because how the hell am I sapposed to know to hop in the twister and rip over to your place for a ride!!!! See ya next weekend bro

Jon

Oh ya now that your boat sounds like a Bayliner what is going to be the next toy? Can we pull the muffler off the F1 golf cart

Hey man, should be a fun weekend. We were talking about getting the river crew together and renting that big aluminum jet boat for a sebago cruise.

As for the mufflers... now I can listen to the tunes you installed last summer

...did you see that turbine powered go cart on ebay? I'd like to have one of them installed in the golf cart

NOT this weekend do it next weekend!!!! I have to go out to the Island this weekend for a install.

Biggus,
What are you running for exhaust manifolds and engine displacement in front of those GGB's?
I am seriously looking at their product. Priced right too!

I'm running CMI's and 700hp 671 blown 468's

Where you able to get down to 89db with one set of mufflers per engine or two?
What rpm loss if any did you see?

Thanks,
Rick

Your welcome Kurt. 89 behind those engines is awesome. What about the RPM and MPH? Did we take anything away?
