BlackBeard1790 Posted August 27, 2019 Share Posted August 27, 2019 Looking into modifying the exhaust on my 2019 Silverado RST 5.3 but I don’t want problems with the drone sound from the DFM. I had that problem with my 2017 Silverado that had the AFM. My local muffler shop claims the Maganaflow will give good sound and I won’t notice any drone. I’m wondering if anyone can vouch for a good setup or if anyone has installed the GM Borla exhaust offered at their dealership? Thanks!
