Stainless Steel Exhaust Header

Crafted from high-grade stainless steel with a mirror-polished surface, it offers superior corrosion and high-temperature resistance compared to traditional cast iron manifolds. The header's design features elongated individual tubes for each cylinder, allowing exhaust gases to exit freely without restriction, thereby eliminating power-robbing backpressure and improving exhaust scavenging. With an optimized 1.75-inch piping inlet diameter and a 2.50-inch collector outlet, this header is designed for maximum exhaust gas velocity and overall flow capacity. It is a direct bolt-on installation requiring no cutting or welding, making it DIY-friendly. The upgrade is expected to unlock noticeable gains in mid-range torque and add an estimated 8 to 15 horsepower, leading to improved throttle response and a deeper, cleaner, more aggressive sport tone without harsh cabin drone. This header is exclusively designed for the 2.0L inline-4 engine models of the 2002-2006 Acura RSX Non Type-S trim and the 2002-2005 Honda Civic Si trim. It will strictly not fit or clear the Acura RSX Type-S trim due to different exhaust port layouts and deck heights, nor will it fit non-2.0L engine configurations. The product is manufactured under strict ISO9001:2000 quality management certification, ensuring top-tier material quality, robust welds, and fitment reliability. Additionally, its precision-machined mounting flange ensures a leak-free seal, addressing common exhaust leak issues found in older, warped stock iron manifolds.
