Does anyone know of mufflers or a combination of mufflers/silencers that could be installed on blown 540/800 horse engines with headers through hull that could bring exhaust noise down to 88 db and not result in engine damage. Turn downs are not an option as they are illegal in our area.

Thanks in advance.

cmi makes a nice one,check their web site.
