Exhaust Header for 2002-2006 Acura RSX Non Type S / 2002-2005 Honda Civic Si 2.0L
Replacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. FLASHARK offers many products to help you create your own custom engine headers. It's really easy and convenient to use: direct bolt-on, no modification needed.

The structural differences between exhaust headers and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.

A1: Yes, this FLASHARK exhaust header is specifically engineered as a precision direct fit for the 2002-2006 Acura RSX Non Type-S (Base trim) models equipped with the 2.0L inline-4 engine, matching the factory exhaust path perfectly. A2: Absolutely. This performance header is fully compatible with the 2002-2005 Honda Civic Si trim featuring the 2.0L inline-4 engine (EP3 chassis), delivering identical high-flow exhaust benefits as it does for the RSX Base. A3: The Acura RSX Type-S utilizes a different high-performance engine exhaust port layout and deck height. This header is exclusively designed for the 2.0L Non Type-S trims and will strictly not clear or align with Type-S models or non-2.0L configurations. A4: By replacing your restrictive stock setup with the FLASHARK high-flow racing header, you eliminate power-robbing backpressure. This optimizes exhaust scavenging, unlocking noticeable gains in mid-range torque and adding an estimated 8 to 15 horsepower for improved throttle response on and off the track. A5: Yes! Designed around precision original equipment specifications, this header offers an easy and convenient direct bolt-on design. It requires absolutely no cutting, welding, or custom modifications to your vehicle, making it highly DIY-friendly for modification enthusiasts. A6: The FLASHARK K-series performance header features a optimized 1.75-inch piping inlet diameter to maintain maximum exhaust gas velocity, transitioning into a 2.50-inch collector outlet for superior overall flow capacity. A7: Traditional factory exhaust manifolds are constructed from thick, heavy cast iron that forces exhaust gases to collide, creating restrictive backpressure. The FLASHARK header is built from lightweight, premium stainless steel with individual elongated tubes for each cylinder, allowing gases to exit freely without restriction. A8: Yes, swapping out your restrictive factory manifold for this stainless steel header yields a much deeper, cleaner, and more aggressive sport tone, giving your vehicle a powerful performance sound under heavy throttle without harsh cabin drone. A9: Definitely. Constructed from high-grade stainless steel with a mirror-polished surface finish, this header offers exceptional high-temperature inoxidizability and corrosion resistance, preventing the common anti-deformation and cracking seen in factory iron manifolds during intense heat cycles. A10: Yes. Older stock iron manifolds often warp and leak around the cylinder head ports over time, leading to power loss and annoying noise. The FLASHARK header features a thick, precision-machined mounting flange that ensures a perfectly flush, leak-free seal to safeguard engine health. A11: Yes, FLASHARK automotive headers are manufactured under strict ISO9001:2000 quality management certification, guaranteeing top-tier material quality, robust welds, and absolute fitment reliability. A12: FLASHARK eliminates middleman markups by designing and manufacturing components directly. This allows us to supply car enthusiasts with high-performance upgrades, premium stainless steel materials, and direct fitment accuracy at a fraction of the traditional market cost.Q1: Will the FLASHARK exhaust header fit my 2002-2006 Acura RSX Base model?
