Stainless Steel Megaphone Cat-Back Exhaust System
Stainless steel megaphone Cat-back means everything from the catalytic converters to the tips; the factory headers and cats stay in place. exhaust for the Chevrolet Corvette C8 ZR1X (2025+), sharing the ZR1's LT7-based twin-turbo V8 and built for street-legal track use. On Fabspeed's dyno it added 44 hp and 68 ft-lb of torque while dropping 39 lb versus the factory muffler. The mandrel-bent T304/T321 tubing steps out from 3 inches to a 5-inch megaphone section before reducing to a 3.5-inch tip outlet, a stepped design meant to cut backpressure, and it's insulated with 2000-degree-rated ceramic fibre wrapped in 625 stainless steel. It retains the factory floating quad tips or can be paired with Fabspeed's own carbon fibre or titanium quad tips, ships with electronic valve simulators to prevent a check engine light, and is emissions legal in all 50 states. Installation is a bolt-on job with no cutting or welding.
