I just purchased the 15" QC from Area P, so far so good. Sounds awesome; however I can't compare it to the 12" or 18" QC. All I know it is def louder than stock. Now if I can only get this jetting correct, but that is for another time.
I picked the 15" based off what other people are saying as well, it is quieter than the 12" but does not look as long as the 18". Good luck !
