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

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.

Aggressive cold start
Deep exotic idle
Crisp high-RPM flat-plane V8 scream
