first off I have the V6 model with solo axle backs. The mufflers look great and sometimes sound great. However after living with them for 5 months they are drivivng me nuts. WOT they sound amazing but any other time especially around 1500rpm the drown and vibration is unbearable. Maybe I'm just noticing more now due to the cold weather, but I feel link I'm driving a Honda Civic with a watermelon laucher on the back. I do have a point to all this babbling, has anyone tried the resonators with V6 axlebacks? How much are they? Will they actually help with vibation and loud drown?
