Designed as a lightweight, free-flowing exhaust for the 2025+ ZR1, the system replaces the restrictive factory rear section with a stepped megaphone design engineered to reduce backpressure, increase performance, and dramatically amplify the character of the 5.5L twin-turbo V8. \u003cbr\u003e\nKey Features\u003c\/p\u003e\n\n\u003cp\u003e+44 HP\u003cbr\u003e\n+68 LB-FT TQ\u003cbr\u003e\n39 lb \/ 17.69 kg weight savings\u003cbr\u003e\nFree-flow 3-inch \/ 76mm exhaust architecture\u003cbr\u003e\nExpands to a massive 5-inch \/ 127mm megaphone section\u003c\/p\u003e\n\n\u003cp\u003eReduces to 3.5-inch \/ 90mm at the tip outlet\u003cbr\u003e\nStepped megaphone design helps reduce exhaust backpressure\u003cbr\u003e\nCNC mandrel-bent construction\u003c\/p\u003e\n\n\u003cp\u003eT304 stainless steel tubing\u003cbr\u003e\nT321 stainless steel flexible bellows\u003cbr\u003e\nCeramic-fiber thermal insulation rated to 2000°F \/ 1094°C\u003c\/p\u003e\n\n\u003cp\u003eThermal insulation wrapped in 625 stainless steel\u003c\/p\u003e\n\n\u003cp\u003eRetains the factory ZR1 quad “floating” exhaust tips\u003cbr\u003e\nOptional Fabspeed quad carbon-fiber or titanium tips available\u003cbr\u003e\nIncludes electronic exhaust-valve simulators\u003c\/p\u003e\n\n\u003cp\u003eSimple bolt-on installation\u003cbr\u003e\nNo cutting or welding required\u003cbr\u003e\nMade in the USA by Fabspeed\u003c\/p\u003e\n\n\u003cp\u003eFabspeed Lifetime Warranty\u003c\/p\u003e \n\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003eProven Performance\u003cbr\u003e\nFabspeed rates the ZR1 Megaphone Cat-Back for gains of:\u003cbr\u003e\n+44 HP+68 LB-FT TQ\u003cbr\u003e\nThe system also removes approximately 39 pounds compared with the factory muffler assembly, delivering both increased output and a substantial reduction in rear-end weight. \u003cbr\u003e\nStepped Megaphone Exhaust Design\u003cbr\u003e\nRather than using a conventional straight-diameter exhaust path, Fabspeed incorporates a unique stepped megaphone configuration.\u003cbr\u003e\nThe system begins with 3-inch \/ 76mm tubing, expands into a huge 5-inch \/ 127mm section, and then transitions down to 3.5 inches \/ 90mm at the exhaust outlet. Fabspeed states that this megaphone architecture helps extract exhaust gases and reduce backpressure. \u003cbr\u003e\nAggressive Twin-Turbo LT7 Sound\u003cbr\u003e\nThe factory ZR1 exhaust is comparatively restrained for a 1,000+ horsepower platform. Fabspeed designed this system to bring considerably more of the LT7’s character to the surface.\u003cbr\u003e\nThe Megaphone Exhaust produces a stronger, more authoritative rumble at idle and transitions into a much higher-pitched, race-inspired wail as engine speed increases. \u003cbr\u003e\nFabspeed reports a sound level of approximately 122.8 dB, increasing to 127.7 dB when paired with its Sport Cats. \u003cbr\u003e\nLightweight Stainless Steel Construction\u003cbr\u003e\nThe system is constructed from mandrel-bent T304 stainless steel and incorporates T321 stainless steel flexible bellows. This combination provides a durable, high-temperature exhaust assembly while eliminating a significant amount of weight from the factory rear exhaust system. \u003cbr\u003e\nAdvanced Thermal Management\u003cbr\u003e\nTo control the substantial exhaust temperatures produced by the twin-turbo LT7, Fabspeed insulates the system with ceramic fiber rated to 2000°F \/ 1094°C, surrounded by 625 stainless-steel shielding. \u003cbr\u003e\nFactory or Optional Exhaust Tips\u003cbr\u003e\nThe system can retain the ZR1’s factory quad “floating” exhaust tips, preserving the OEM rear appearance.\u003cbr\u003e\nFor a more customized look, Fabspeed also offers optional:\u003c\/p\u003e\n\n\u003cp\u003eQuad carbon-fiber exhaust tips\u003cbr\u003e\nQuad titanium exhaust tips\u003cbr\u003e\nCarbon-fiber tip surround\u003c\/p\u003e\n\n\u003cp\u003e \u003cbr\u003e\nElectronic Valve Simulators\u003cbr\u003e\nBecause the Megaphone system eliminates the factory valve-controlled rear muffler arrangement, Fabspeed includes electronic valve simulators designed to prevent a related Check Engine Light. \u003cbr\u003e\nBolt-On Installation\u003cbr\u003e\nThe system is designed as a direct bolt-on cat-back upgrade with no cutting or welding required. \u003cbr\u003e\nProfessional installation recommended.\u003cbr\u003e\nWarranty\u003cbr\u003e\nBacked by the Fabspeed Lifetime Warranty. \u003cbr\u003e\nVehicle Fitment\u003cbr\u003e\n2025+ Chevrolet Corvette C8 ZR1\u003c\/p\u003e\n\n\u003cp\u003eCoupe\u003cbr\u003e\nHTC \/ Convertible\u003cbr\u003e\n5.5L Twin-Turbo LT7 V8\u003c\/p\u003e\n\n\u003cp\u003eFabspeed specifically lists the exhaust for 2025+ C8 ZR1 Coupe and Convertible models.
