CORSA Xtreme 3.0in valved axle-back exhaust for the 2024-2025 S650 Mustang GT 5.0L Coyote V8. CORSA-engineered cast valve assembly and custom-tuned mufflers deliver an aggressive note that runs 5 decibels louder than stock, while patented RSC technology keeps the cabin drone-free at cruise. Built from 304 stainless steel with a 3.0in Double Helixx dual-crossover X-pipe, it outflows stock by nearly 17 percent and bolts on in about an hour. Made in the USA.
