Only every once in a while i can hear a slight tone change with 14" when the mds kicks in. Have to do some testing to see what exactly does it. But 95% of the time, you cant even tell when mds kicks in inside the cab. Cant say about outside because i wont even let my wife drive my truck to do a driveby! haha.. But seriously, it is not enough to even bother with, if you want a good tone, you wont be sorry you got a muffler just because of the mds situation.
