What did you do to your 21+ T1XX today?
Hello! Pretty new to forum. Just added a magnaflow muffler 10416 on my 2023 Yukon Denali and it definitely sounds really good. Low growl, not too loud. It’s the perfect balance and I’d recommended it to people thinking of getting a full car back. Try this first! I’m sure you’ll be happy- ACHUN717
