I Have Them On Mine 598/800 Hp Under water till you got on plane still pretty quiet cause they face the water and the sound gets muffled a little, but still loud enough

I'll give you the other side of it. I just removed some 4.5" turn downs from my boat. They worked flawlessly and were quiet when not on plane, but would soak about the back 5 feet of the swim platform from the spashing. On plane, they were quieter than before (Stellings dry pipes) and had no effect on performance. If the PoPo were enforcing noise laws around where I live, they would still be on my boat....but they don't and I'm loud as chit again.
My neighbors love me.....what can I say?????????????

I'm leaning toward using the turn down pipes....Thought about asking Stelling for pipes with GGB ? inline mufflers...Randy provided a good quote,though he doesn't have a CMI flange ring...customer furnished item...Unknown burn through in the mufflers and then potential reversion bothers me a bit.....I'm not sure the Stelling ---GGB combo will pass the DB test ...Maybe someone here knows.
