Let me preface this by saying that this was sort of an impulsive purchase and although I did do some research on the TRD exhaust I should have maybe waited and heard it in person.
Today I purchased a TRD exhaust for my 14 DCSB and I was surprised by the sound. Since I hadn't heard the exhaust before I really don't know what I was expecting but that wasn't it. At highway speeds it sounds good but driving around the city it seems to drone or resonate a little too much for my liking. Hopefully the exhaust tone changes within the next few hundred miles if not I may have to go back to stock.
I've drove approximately 600 miles since installing the TRD exhaust and I must admit that it's sounding a lot better. It has a good sound at low RPMs and low noise at highway speeds. I drove from Vegas to LA yesterday and the drive wasn't loud at at all. At this point I would recommend it to anyone who is interested in an aftermarket exhaust.
