Owners who want more sound from the 3.6L LF4 twin-turbo but prefer a simpler install than a full cat-back will find this axle-back a practical fit for the 2022-2025 CT4-V Blackwing. It installs with a cut-and-clamp procedure at the axle-back section and connects to the factory Dual Mode Active Exhaust module to preserve valve operation. Carbon fiber tips with polished accents add a motorsport-style finish to the rear fascia.
