Catback exhaust systems guaranteed to fit your 2020-2026 Chevy Silverado 3500HD. Single and dual-outlet configurations from MBRP, Borla, Flowmaster, and MagnaFlow covering both the 6.6L L8T gas and 6.6L Duramax diesel.

Will a catback exhaust trigger a check engine light or void my warranty? No. Catback systems install behind the catalytic converter, leave all factory sensors untouched, and do not affect your powertrain warranty under the Magnuson-Moss Act.
