This is the most refined sound for the OEM mod..ofcourse it wont be as loud as other methods, but it also wont drone and rasp.

, but this has been discussed at length and you're wrong. While the mod retains the Heimholtz pipes they are essentially useless as the volume amplified by the mod would require a longer pipe to combat drone. So straight pipes are identical to the ACM mod. I have had a set of stright pipes and they really are just loud, really don't drone and do sound sick, but a good set of mufflers always prevails IMO.

But the vid is also skewed as it's in a garage.
