CORSA's Pro Series cat-back for the Ram 1500 RHO is a 3.0 inch 304 stainless steel true dual system with two mufflers, integrated X-pipes and CORSA's No-Drone RSC (Reflective Sound Cancellation) technology for a quiet cabin at cruise. Tuned specifically to the RHO's 3.0L twin-turbo, it delivers an aggressive Sport-level note on start-up and hard acceleration while staying drone-free on the highway, and it outflows the stock system. It bolts on in about an hour and is made in the USA.
