Sound is sweet ! Its not ricey loud, but u can notice the difference ...its a more "classy loud" , if you will.
Also, after mod, i can now hear the "woosh" of the turbos as they spool and that sounds amazing
never heard this sound before prior to modding !
I took a short idling vid before / after mod.... ill put this up if u guys want ?
Yes, Is the drone heavier? Upload or link!
