Description
The CORSA Xtreme Exhaust System 14358BLK is a dual-exit rear axle-back kit for 2016–2019 Cadillac CTS-V sedans with a 6.2L/376ci V8 (VIN code 6), automatic transmission, and rear-wheel drive. It is designed for the dual rear-exit application and is not universal.
The system uses 2.75-inch tubing and includes two chambered mufflers, each with a single inlet and single outlet. CORSA’s straight-through design and patented reflective sound-cancellation technology are intended to tune out low-frequency exhaust drone while retaining a crisp exhaust sound. The design also reduces backpressure, which can allow the engine to produce more horsepower and torque; no specific output figures are provided.
