Description:
Brand new, never installed Borla 60679 optional S-Type muffler. Manufactured 02/28/24. Still in original factory box with packing.
This is not a complete cat-back exhaust. It is the optional rear muffler that Borla designed to change the sound level on their 2019–2023 Silverado/Sierra 1500 6.2L systems.What it does:
Replaces the polyphonic harmonizer that sits behind the main muffler on a Borla ATAK cat-back. Installing this muffler quiets the system down to the classic S-Type sound (less aggressive, less drone).Fits only:
2019–2023 Chevrolet Silverado 1500 / GMC Sierra 1500
• 6.2L V8
• Automatic transmission
• 2WD or 4WD
• Must already have a compatible Borla cat-back (140773 / 140775 family, etc.)
