Which ones louder Gibson or CMI mufflers
I have a new supercharged 540 being built for my hallett and need some new mufflers. I currently own some IMCO mufflers however they are not rated for the 750hp that I'm expecting. I was thinking on getting the Gibson bulletts with external flappers or the CMI mufflers. My IMCO mufflers set in the water 1 to 1 1/2" inches at idle and I need some protection from possible water indigestion.
Does anyone know which muffler is quieter at cruising speed (45 - 55)? I can get the CMI for about $950 and the Gibson are a lot less at $570. I just wanted to get the quieter muffler for my wife even though both are gong to be too loud for her.
Any suggestions????

I need protection from water ingestion due to standard risers and the exhaust mufflers will be touching the water at idle. I can either run Bullets with rubber flaps flaps or CMI's.
I called some vendors and they all say CMI is a little quiter but no one has hard data.
