The reason I ask about the silencer is for when the wife is cruising with me as she doesn't like an aggressive exhaust as much as I do especially on the long cruises. Also I was hoping the silencer would help with the drone as I am sure this exhaust has the drone issue! How difficult is it to remove the silencer? I like the exhaust, the sound, and the performance but there are occasions where I would like to "turn it down" a little :). My other exhaust I am looking at is the SZ and Labree 3" systems. Any additional advice would be appreciated. Thanks again!
