Does anyone know the length of the OEM muffler? I want to replace my muffler with an Aerochamber direct replacement muffler, which is 3" In/Out and 22" case length ... would that work? This is for my 5.3L Sierra NBS 2x4 ECSB, thanks!

  I have no direct experience, but everything I have seen indicates Silverado and Sierra bed geometry is identical.

- 2024 Silverado HD shell on a GMC fitment??
  
  By cseaman · Posted 2 hours ago
  
  Has anyone had any luck swapping a Leer or equivalent shell between the current gen GMC/Chevy HDs? Hopefully specific to the standard 6'9" bed. I had an Overland Vehicle Systems shell on my 1500 AT4 and I know those fit the Sierra and Silverado, with or without the Multi-Pro tailgate. That said, I think the Leer shells are made to fit all the way over the bed caps as opposed to on them with some room to spare like OVS. Some 1500 owners reported some change in coverage over the rear tail lights..but that's 1500 specific.
