25-27+ C8 Corvette ZR1/ZR1X Competition Downpipes - Soul Performance

Fits 2025+ C8 Corvette ( ZR1 Models )

Description: 

Unlock the full exhaust performance potential of your 2025+ Chevrolet C8 Corvette ZR1 or 2026+ ZR1X with the SOUL Performance Products Competition Downpipes, available under Part Numbers CHEV.C8.ZR1.CBP and CHEV.C8.ZR1X.CBP. Engineered specifically for the 5.5L LT7 twin-turbocharged V8 engine, these premium catless downpipes completely eliminate the factory catalytic converters to maximize exhaust flow, reduce backpressure, and deliver a dramatically more aggressive turbocharged V8 exhaust note. Featuring large-diameter 3.5-inch mandrel-bent tubing that transitions smoothly to 3 inches for compatibility with the factory rear exhaust system, these competition downpipes are designed for maximum performance in dedicated off-road and racing applications. Independently tested by SOUL Performance Products, the downpipes delivered gains exceeding 100 wheel horsepower and 130 lb-ft of torque at 4,000 RPM, with approximately 55 wheel horsepower and 30 lb-ft of peak power and torque improvements. Each assembly is handcrafted in the USA using thick-wall T304L stainless steel, precision back-purged TIG welding, and integrated 321 stainless steel heat shielding for exceptional strength, durability, and thermal management. Weighing approximately 32.5 pounds less than the factory catalytic converter assemblies, these SOUL Competition Downpipes provide a significant performance-focused exhaust upgrade for C8 Corvette ZR1 and ZR1X owners. Both model-specific configurations are available directly on this product page, with the ZR1X version incorporating additional exhaust gas temperature sensor provisions. Professional installation and appropriate engine tuning are required. Intended strictly for off-road and competition use where permitted.
