I would not recommned getting resonators, you won't need them. My NA could use them way more than your TT. You can hear my car from miles away it sounds like a german tank and everyone around hates it. It louder than my roommates WS6. Yours would be too quiet with resonators. I plan on adding a TT to my collection soon and keeping the NA as my DD and will def opt out of resi's for the TT as well.
