Maximum Power. Exotic Sound. Built for Competition.

Unleash the full potential of your 2025–2026 Chevrolet Corvette C8 ZR1 or ZR1X with the SOUL Performance 3.5" Competition Exhaust Package. Designed from the turbochargers back, this complete competition exhaust system maximizes exhaust flow, turbo response, and the unmistakable sound of Chevrolet's twin-turbocharged flat-plane crank LT7 V8.

Built entirely in the USA from premium T304L stainless steel, the SOUL Competition Exhaust Package dramatically reduces weight while delivering race-proven horsepower gains, sharper throttle response, and an exotic supercar soundtrack unlike anything offered by the factory exhaust.

Whether you're chasing lap times, building a high-horsepower street car, or simply looking for the ultimate ZR1 exhaust system, the SOUL Competition Package delivers uncompromising performance.

 

DYNO-PROVEN PERFORMANCE

Designed to eliminate factory exhaust restrictions, the SOUL Competition Exhaust Package unlocks substantial power gains while dramatically improving exhaust flow.

Performance Highlights

• Over 125 WHP maximum gains with exhaust system alone
• Up to 173 WHP gains with supporting bolt-on modifications and tuning
• Up to 209 lb-ft of torque gains with supporting modifications
• Faster turbo spool
• Sharper throttle response
• Increased exhaust flow from turbochargers to tips
• Improved power throughout the RPM range

The full 3.5-inch turbo-back design provides significantly greater flow capacity than the factory system, helping the LT7 engine breathe more efficiently under all driving conditions.

EXOTIC FLAT-PLANE V8 SOUND

The factory ZR1 delivers incredible performance—but its sound is heavily muted by restrictive catalytic converters and factory exhaust components.

The SOUL Competition Exhaust Package transforms the driving experience by unlocking the true character of the twin-turbocharged flat-plane crank V8.

Sound Characteristics

• Aggressive cold start
• Deep exotic idle
• Crisp high-RPM flat-plane V8 scream
• Increased turbo spool and blow-off sound
• Richer exhaust tone throughout the powerband
• Straight-through performance design
• Minimal interior resonance for improved driving comfort

Designed through extensive acoustic testing, the exhaust produces a refined exotic tone worthy of a modern supercar.
