I listened extensively to sounds clips online off all exhausts (Idle, revving, driving, in cabin outside cabin, etc) before purchasing the RPI GTS system.After I purchased, I can say that I love it. It has a nice deep growl, not raspy or obnoxious. No drone, can have family in the car and it's not over the top, but sounds nice and aggressive when flowing.

The design looks a lot better for efficiency and great price. I liked the look of the mufflers better too. Has a nice aftermarket look over the OEM stamped look. Just my personal preference.
