25-27+ C8 Corvette ZR1/ZR1X Performance Cat-Back Exhaust - Soul Performance

Fits 2025+ C8 Corvette ( ZR1 Models )

Description: 

Unleash the distinctive sound of the 5.5L LT7 twin-turbocharged V8 engine with the SOUL Performance Products Rear Cat-Back Exhaust System, Part Number CHEV.C8.ZR1.ESX, designed for the 2025+ Chevrolet C8 Corvette ZR1 and ZR1X. Engineered to deliver improved exhaust flow, enhanced throttle response, and a significantly more aggressive flat-plane-crank V8 exhaust note, this premium non-valved exhaust system replaces the factory rear exhaust assembly with a lightweight, high-performance alternative. Featuring a large-diameter design that begins with 3-inch connections at the factory-style downpipes before expanding to 3.5-inch primary exhaust outlets and 3-inch secondary outlets, the system is designed to reduce exhaust restriction while accentuating the LT7 engine's unique exhaust characteristics and turbocharger sounds. Constructed from mandrel-bent, thick-wall T304L stainless steel with precision back-purged TIG welding, each assembly is handcrafted in the USA for exceptional strength, durability, and long-term performance. Advanced metal 3D-printed 316L stainless steel tip outlets provide optimized exhaust flow into the factory bumper-mounted exhaust tips. Weighing approximately 40 pounds less than the factory rear exhaust, this SOUL Performance system offers an excellent combination of improved exhaust sound, reduced weight, and premium construction. Complete with factory exhaust valve relocation brackets, wiring harness extensions, replacement gaskets, and installation hardware, this system provides a direct-fit performance exhaust upgrade without requiring replacement of the factory catalytic converters.
