Stainless Steel Exhaust Header

The SPELAB Exhaust Header is engineered to enhance both engine performance and exhaust acoustics for 2009-2013 Nissan 370Z and 2008-2013 Infiniti G37 models equipped with the 3.7L engine. Its design focuses on increasing horsepower and refining the exhaust note, offering a noticeable improvement for enthusiasts seeking better performance. This ease of installation ensures a convenient upgrade path for your exhaust system. Exhaust headers, like this SPELAB model, are presented as a superior alternative to exhaust manifolds. Unlike manifolds, which can create performance-hindering back pressure, headers provide each cylinder with its own tube, allowing exhaust gases to exit more freely and efficiently. This design is crucial for maximizing engine output and responsiveness.
