I just got the Vibrant Ultra Quiet resonators installed today and the rasp and snappy-ness is gone! The overall volume of the exhaust is quieter for sure, but the tone is so much smoother. The volume is closer to what it was before I had catted down pipes installed. That said, I know that the tone and volume is likely going to change over the next few weeks so as long as the rasp stays away, I'm good with it getting louder.
As a reminder, my current setup is test pipes, to catted down pipes, to the Magnaflow 11385 xpipe, to the new Vibrant Ultra Quiet resonators (in place of where the stock mid-muffler was), and finally the stock rear mufflers.
And below we got a pretty crappy sound clip. This is after a 25mins drive from the exhaust shop to my house. With the rain and my hvac running, there is just a lot of background noise (sorry).
