Muzzy Whisper cores

i am in the information gathering process now in researching dbs of exhausts. i would like full muzzy duals, but an worried about the db level of it. My wife rides with me a lot and we like to listen to music or have he ability to have a conversation while riding. Does anyone know what the db level is on a full muzzy with duals? The muzzy website lists dbs as 94 dbs. I wanted some real life db levels of theirs if anyone has them….On the muzzy website under the maverick section, they have "whisper cores" as an add on option. They advertise that they lower dbs by 3-4 dbs. Does anyone know if these will work on the outlander dual exhaust?…..is a slip on quieter than duals or about the same?…….I tried to call muzzy and no one answered and also tried to email them and didn’t get a response to these questions:th_smiliepullhair:…
