Description
Enhance the tone and performance of your 2024 Mustang GT Convertible with the CORSA 3.0" Axle-Back Exhaust System featuring 4.5" Polished Straight Cut Tips. Designed specifically for the 7th Generation S650 Mustang GT 5.0L Coyote V8 without Active Valve Exhaust, this system delivers improved sound character, weight savings, and industry-leading drone control.
Constructed from premium 304 stainless steel, this dual rear exit axle-back system features straight-through custom-tuned mufflers engineered exclusively for the new-generation Coyote engine. The Sport axle-back bolts directly to the factory resonated mid-pipe and produces a moderately aggressive tone during cold starts and heavy acceleration, while maintaining a quiet, comfortable cabin at cruise thanks to CORSA’s patented No DRONE RSC® technology.
The straight-through muffler design increases exhaust flow by up to 46%, helping maximize the performance potential of stock and modified setups alike. Finishing the system are quad 4.5" dual-wall polished stainless steel straight cut tips that provide a clean, aggressive rear appearance for the Mustang GT Convertible.
