Corsa Performance Exhausts has designed an exhaust system complementary to the exterior styling of the 2009 Cadillac CTS-V. It features a dual rear exit with single 4-in (102-mm) pro-series tips etched with the Corsa logo. There are two versions of the system: touring (part #14940) and sport (part #14941). The touring exhaust system delivers a deeper, more refined muscle-car sound, while the sport exhaust system produces a wide-open, aggressive tone. The Cadillac CTS-V system is engineered using reflective sound cancellation technology to produce a bold performance note with no interior resonance. Delivering a performance gain of 16 hp (12 kW) and 22 lb·ft (30 N·m), the system is 40% lighter than stock, according to Corsa. It features 2.5-in (63.5-mm) straight-through design styled exclusively for the Cadillac.
