4-2-1 Stainless Exhaust Manifold

The Zero Fighter Stainless Exhaust Manifold is a meticulously engineered 4-2-1 type exhaust manifold specifically designed for the HONDA EK4 and EK9 models. Developed through extensive research and real-world testing in demanding circuit racing environments, this manifold aims to optimize engine performance across the entire RPM spectrum. Its design focuses on achieving stable exhaust efficiency and balanced performance from low to high RPMs, crucially eliminating the common torque dip experienced in the medium and low-speed ranges. Beyond its performance enhancements, the lightweight construction of this manifold contributes to an efficient demonstration of engine power and improved responsiveness. The manufacturer also highlights a particular focus on sound quality, noting that it produces a VTEC sound reminiscent of a racing car. The product is actively used and recommended with confidence by the manufacturer on their own race cars, including their EK9 durable specification car No. 1. It is important to note that this product is designated as a dedicated part for competition vehicles. While it generally conforms to safety standards, compliance with vehicle inspections may not always be guaranteed.
