Description
The CORSA Sport Valved axle-back exhaust system is configured for Cadillac CT4-V Blackwing. This version pairs 3-inch piping with a dual rear exit layout. This listing includes Polished tips.
Sound and design
Sport tuning delivers a pronounced exhaust note under acceleration, with attention to cruising comfort. It suits an owner who wants a more noticeable exhaust character without choosing the most aggressive available sound configuration. Reflective Sound Cancellation (RSC) technology targets unwanted cruising resonance. The resulting cabin sound depends on the complete vehicle and exhaust configuration.
The axle-back configuration focuses the change on the rear exhaust section. It is useful when selecting a different rear muffler and outlet arrangement while retaining the upstream system specified for the installation.
