First post-
Recently purchased an '88 Rogers (454) 21' jet / Open / 4" thru transom with flappers

I'm a previous owner of 2 other similar boats, but don't recall the exhaust being so loud, or maybe I liked the noise back then-
25 years later, Now introducing grandchildren to the river.....maybe I'm getting old & would like a little conversation with-out yelling over the loud exhaust.  Also it would be nice to listen to music while underway.

Any suggestions on silencers or mufflers would be appreciated.
