I have a set of those on order, but I have my doubts they will work as well as advertised. 6 db is a HUGE difference. Decibels work on a logarithmic scale, so every 3 db's is a doubling of the noise (23 db is twice as loud as 20 db. 30 db is 10 times as loud as 20 db, and 40 db is 100 times louder than 20 db).
If I get the full 12 db, that would put me around 91-92 db, but I seriously doubt I'll get that much reduction. 6db would be great, that would put me at 97 - which is way more tolerable. I would love to be around 95 db or less. anything over 95 -96 for prolonged periods will give you permanent hearing damage.
Have a look here below at this link.
It says they lower decibels 6-12db but I am guessing that even 6db would be maximum on them, they would help a bit but your pipes would still be in the 98db range which is still loud. If they do lower by 12db then all the better. The other option would be to reinstall the quiet stock pipes, which I did but went back to loud pipes again because I could not stand the quiet pipes, too quiet for me to hear when to shift gears, I shift gears by sound of the pipes. You might try those Hard Kore Quiet baffles but try to live with the sound you get. A 6db decrease is not all that much but it's worth a try.
