Hey man, I have the Borla touring (GM performance exhaust) for my 19 AT4 5.3. I absolutely love it but I wish it was a tad louder. I've read a lot of threads about the S type being too loud. I as well was wondering if I could swap the mufflers between the touring and S type. I may buy an S type muffler and switch out my touring muffler but Im not sure if that can be done. The touring has a nice tone, and isn't obnoxious. But then again, Im young and kind of dig the tone of the S type.
I recently took my 19 AT4 stock off-roading. Unfortunately I damaged my truck. Before I explain what happened, let me disclose that it was completely my fault and I am not blaming the truck or anyone besides myself lol. I love my truck! I was at the off-road park for about 30 minutes. I did some minor rock crawling (minor as in driving over rocks no larger than 6 inches in width).

I purchased the GM Performance Exhaust upgrade for my 2019 GMC AT4 5.3. Its the Cat Back exhaust. I believe its similar to the Borla Touring Exhaust. However, I love it but wish it was a tad louder.

Hope this helps! Also I get no drone on the highway.
Yeah ive seen a lot of people have issues with the lift on the AT4/trailboss. Wondering if I could squeeze a 2 inch leveling kit on my AT4. Seen people go with 1.5 and I wonder if its so they wont have any issues. What do you owners who have leveling kits think?
19 AT4 5.3 with tech package and 20s, so far only mods are the windshield decal. Love the truck drives surprisingly smooth for an offroad oriented trim. I have taken it offroad and it impressed me. #RideOnT1s!
