Exhaust Headers vs. Stock Exhaust Manifolds For Infiniti G37 / Nissan 370Z / 350Z

Factory exhaust manifolds on the Infiniti G37 and Nissan 370Z/350Z are designed to meet noise, emissions, and cost requirements rather than maximizing performance. While reliable, they often restrict exhaust flow and limit the engine’s true potential.

• Improved engine breathing: Aftermarket headers reduce exhaust restriction, allowing spent gases to exit more efficiently.
• Stronger throttle response: Less back pressure helps the engine respond faster to driver input.
• More usable power: Gains are felt throughout the rev range, not just at peak RPM.
• Enhanced driving experience: Better flow contributes to a more engaging and responsive feel behind the wheel.
• Optimized sound character: Compared to stock manifolds, headers produce a deeper, more performance-oriented exhaust tone.

For Infiniti G37 and Nissan 370Z/350Z owners, exhaust headers are a foundational upgrade that enhances both performance and driving enjoyment without changing the engine’s core reliability.
