Fabspeed Stainless Megaphone Exhaust for Corvette C8 ZR1

Replace the matching ZR1 rear muffler with a fixed-volume megaphone cat-back. Its stepped tubing expands before tapering to the floating-tip outlets, with a pronounced exhaust note and no original selectable quiet mode. Fabspeed Motorsport designs performance exhaust systems, air intakes and ECU tuning in Fort Washington, Pennsylvania. Porsche and other sports-car applications are developed through dyno testing, road evaluation and racetrack work.
