Great for 2019 Silverado 5.3L

I have been using Magnaflow mufflers for over twenty years. High quality stainless steel, perfect welds and I like the sound. Quiet at idle and cruising, but sounds terrible under hard acceleration. I chose the 5x11 case because I prefer the quieter side. 4x9 would sound very harsh. You can't go wrong with this.

Pros
