I recently got 2 pair of what the previous owner called GGB bullet style exhaust tips. There are no markings or logos on them but appear to have the GGB insert welded inside the tip. Anyone ever heard of these or run them? I plan on running these on a formula that currently has silent thunder. It is too quiet for my liking now but straight tips are way too loud. Will these end up somewhere in the middle or will it end up sounding more like a straight through tip?

My neighbors Formula 353 with twin 500 has Gibson clamp on mufflers (BIG looking). I think that is what your referring to. Go to there website and see if that's them. Sound Ok

Those look like ggb. Had them on last boat and were great. Too quit when flapper was new, but in 10 hrs they were fine

Thanks. There seems to be very little info out there on the GGB's. From what I can see, the gibsons look similar but they don't have the 4 water relief holes.

I had the GGB's with turndowns on my previous boat as well.. Didn't rob any power on the Dyno at 600 hp...

You would think a barn that big would at least have triples!
