Heres another muffler story: I had a overpowered Baja 272, ran a best of about 99.5 gps. Had 5" stellings style tails, with no mufflers it was give you permanent hearing damage/get pulled over loud. So the water was added right near the tip about 5" past the transom. So it wasnt a "dry" exhaust but real close to it. Put on a set of GGBs, boat noise was tolerable but didnt lose measurable speed when turned up to full kill. Left one of them on bottom of Higgins lake one day at 80+ mph in 75+ feet of water so no chance of finding it. Funds were kinda tight, called GGB, they no longer made clampon mufflers for whatever reason. Bought a set of Gibson clampons cheap new. Expected boat to lose considerable speed, they had a fairly small ID compared to body size. I still broke 99 mph with full kill pulley on, I was actually SHOCKED. BTW, if anyones looking for one GGB 5" clampon, I still have one. I used those same gibsons on my dyno full dry for a while, they tamed noise down, wasnt probably quiet enough to pass a db test with water cops but was better then open headers as far as noise, Smitty
