Is it worth putting the GM "performance" exhaust on my AT4?

[ahopkins]

Only had my at4 for a few months now but I want a deeper, louder sounds driving it down the road. Gots to let everyone hear the 6.2 V8!! I dont want to void my warranty on anything though. Anyone done that yet? Or have any suggestions?

I had the dealership where i purchased my 2021 6.2 AT4 put on the Borla Cat Back Exhaust (GMC Part # 19419433). Doesn’t effect warranty at all. In my opinion, the sound is 100x better. You can hear it here (as good as video allows):

Oh lord that is a heavenly sound!!! Thanks!

My 2021 6.2 AT4 came with the factory cat back option. Is that the Borla or something different? Either way it sounds amazing, I love it.

I put the Borla ATAK on mine over the weekend, along with a K&N series 63 CAI. Oh lord, it’s loud!! Pretty sure I went full redneck! I will upload a video if I can figure out what file size is allowed.

Please do. I'll be getting my AT4 hopefully by the end of the month and throwing on a exhaust will be my first upgrade.

My 6.2L has the factory performance package installed on it. I wanted a little rumble on this truck and I could not be happier with it. Just the right amount in my opinion.

I actually saw your video on YouTube before I joined this forum and thought the sound was awesome. Really like all your mods!

I'm heading in that direction myself, but first I'm going to try the muffler delete this weekend. Then I'm hoping I'll be satisfied and saved money, OR if I hate the sound....or more importantly my wife hates it....then I can justify the expense of the cat back borla LOL

Great plan!

So did the delete. It sounds GREAT at start up and when you're on the gas. However it does drone a bit when you're going up a hill, I'm worried that towing will drone as well. Not sure if I'm leaving it or if I might add some type of muffler. Gonna give it a week.
