### ⭐⭐⭐⭐⭐ Awesome Exhaust!!!!!

Installed it on my 2016 Silverado 1500 LT. Exactly the right amount of sound i was looking for. Really good aggressive but not overwhealming sound.

### ⭐⭐⭐⭐⭐ I'm excited for cold starts. A very mellow rumble
*by A***R on August 5, 2025*

I'm running this on a 2012 6.2 denali. It sounds amazing. Just enough to where you can hear it. But not too much where the sound is obnoxious. Keep the resonator, delete the third cat, and you have a very tasteful sound. Even none car people have complimented it. The box looks like it survive world war II. I dont know what it went through in shipping. the muffler itself had a couple small dents but I didn't mind. It was still usable
