The FRS I purchased had the TRD catback already installed. It sounds great but 3 hours on the highway and the headache doesn't stop for hours after exiting the car. If I were to have purchased the catback, I would have purchased something else for 2 reasons: 1. Better values out there. 2. I love driving the car but the drone between 2-3k RPM (typical driving RPM I might add) is bad.
You can solve the drone with a Helmholtz resonator but there are less expensive catbacks with the Helmholtz resonator already integrated.
I didn't want to junk the TRD catback, so for now, I have sound dampened the entire car, which has helped tremendously. Not only is the drone less noticeable, daily driving is far more civilized.
