I guess it could depend it you get the mufflers only vs full exhaust.
I just got the race mufflers with 90mm and think the sound db's are perfect. It is louder when cold just like the stock exhaust for 30 seconds or so but I love the look and sound so far.
Lucky we all don't like the same thing, life would be pretty boring ;-)
