5.3l TB muffler swap for magnaflow 12249


Recommended Posts

Even all,

 Looking to swap the stock muffler in my 2021 5.3 TB. I had a 2016 sierra 5.3 and swapped the stick muffler with Magnaflow muffler and it sounded amazing. No drone no obnoxiously loud in the cab. Curious if anyone has swapped this muffler on these generation trucks.

I put a 14" magnaflow on my 2020 5.3l. I don't remember the exact model #, but it sounds great. Not obnoxious and waking up the neighbors, little drone, and when you need someone to know you're there, they will!
