so wait the Dinan is not proven?? there not passionate about the gains of there products??
also those little things may reduce droning but it still drones at some points, where the Dinan doesn't drone at all, so i would say they have to be doing something right
no offense but your statement just doesn't make sense to me. AA is a good company but there are others that are just as good and just as passionate

If you look at the system itself those little pipe things next to the muffler is to reduce the droning.
