I’ve heard great things about the Borla systems—specifically the 19433761 and 19433763 models, with the added bonus of a lifetime warranty. If you're looking for a bit more of an aggressive sound, I’d go for the black tip version for a more sleek look. The GM-branded system is a solid option too, but the shorter warranty could be a dealbreaker if you're planning to keep the vehicle long-term. Definitely sounds like you got a good chance to hear it in person, which is always the best way to decide!
