Peace, mercy, and blessings of God be upon you. I have a catback, AWE pipe, and an electronic valve custom-made by FDR Garage. The catback is guaranteed in all aspects. The AWE pipe is guaranteed except for a light weld due to the removal of the valve, then I reinstalled it, and a light dent on the differential due to hitting the ground (it doesn't harm at all). The parts fit: Sierra 2019 Sierra 2020 Sierra 2021 Sierra 2022 Sierra 2023 Sierra 2024 Sierra 2025 Sierra 2026
