So, as stated in the beginning, my BRZ is my daily-driver.
That being said, it has to be comfortable enough for my commute to work, and my wife has to approve when we go out for date-night.
After the TRD cat-back, she wasn't very happy. Lots of drone, and it was a little loud. So I decided to try and remedy the situation by adding a second resonator to the front pipe.
As luck would have it, the self-serve shop that I go to had an extra OEM front-pipe lying around after someone installed an aftermarket one. They know me pretty well there, so they let me cut out the resonator (leaving the cat, that they actually wanted).
After finding a suitable spot for the resonator that wouldn't interfere with the chassis or any moving parts, we cut/welded it in.
Thoughts: The volume didn't decrease that much, as resonators are more focused on cancelling out noises, instead of reducing volume. But oh man! The drone is gone!
I'm still gonna keep an eye out for other solutions that might reduce the volume just a little bit more, but for now, i'm very happy.
