So I shot this today for all of you wondering about the tone/sound difference with my Borla S-Type Cat-Exhaust several weeks later. Facts: - I've driven over 2K miles since the install 3 weeks ago. - I recognize the control areas are different with one being in the complete outdoors and one in an open garage. - Control areas are in a fairly quiet area. I'll take another video another 3-4 weeks and another 2K - 3K later as well as a drive around inside the cabin and outside the cabin. I hope you enjoy!
