Fabspeed Megaphone Catback Exhaust System for C8 Chevrolet Corvette ZR-1

Fabspeed’s Stainless Megaphone Catback Exhaust for the C8 Corvette ZR-1 is a street-legal, track-focused, lightweight system engineered to wake up the LT7 like nothing else. This all-out race-bred cat-back transforms the 5.5L V8 with twin 76 mm turbos from the subdued OEM tone to a thoroughbred soundtrack — delivering a deeper, more authoritative rumble at idle and a higher-pitched wail as the revs climb. Built in T304L stainless and optimized for flow and response, it unleashes the ZR-1’s character while preserving everyday drivability. For maximum power and sound, pair it with Fabspeed’s Sport Cat Downpipes to further cut backpressure, sharpen throttle response, and amplify the exhaust note.
