Daysyore Exhaust Header for 2003-2007 Nissan 350Z/G35

Headers are aftermarket exhaust components that reduce backpressure for better performance at high RPMs, while exhaust manifolds are factory-installed parts designed for balanced performance, fuel economy, and efficiency.

• Headers often reduce exhaust backpressure, resulting in improved performance at high RPMs
• Exhaust manifolds retain some backpressure to ensure driving performance across a wider range of RPMs
