2019 GMC Sierra Borla ProXS Muffler

The 2019-2022+ GMC Sierra and Chevrolet Silverado 6.2L trucks are nearly silent. This is thanks to dual valves that block up way too much of the exhaust in an effort to muffle the V8 roar. I'm going to fix that with a Borla ProXS 40359 muffler. I'll cut off these ridiculous flapper valves (adaptive valves) and make it sound like a nice V8 again! Who wants a V8 with no rumble? Not me! Any reputable muffler shop should be able to help with this fix if you can't DIY it.
