HKS, Catted Downpipe (Metal Catalyzer) Honda Civic Type-R FL5

Unleash the true potential of the CIVIC TYPE R with the new Metal Catalyzer!! Features The OEM part uses a fine-mesh ceramic catalyst (600 cell +400 cell), while the HKS product incorporates a low-density metal catalyst (150 cell x2). Utilizing lost wax casting for the outlet, the vehicle-specific design significantly reduces exhaust resistance The exhaust efficiency design and optimal metal ratio achieves both purification performance and low exhaust pressure. Earning official exhaust gas certification from official institutions. A specially designed heat shield is included as a countermeasure against heat damaged. This product is buffed to a mirror finish and TIG welded. Demonstrating attention to detail. Performance Comparison In flow bench testing, the HKS Metal Catalyzer (referred to as the HKS Catalyzer) achieved approximately 51% lower exhaust resistance compared to the stock catalytic converter. Sound Comparison Installing the HKS Catalyzer, the sound emitted from the muffler will change. In terms of proximity exhaust, the mid- and high-frequency ranges for both the stock muffler and the HKS muffler (LEGAMAX Sports) (Abbreviation: LMS) has been tuned to produce a sportier sound. While replacing the catalytic converter tends to increase proximity exhaust sound, combining with the LMS ensures compliance with safety standards, providing a worry-free experience. ** https://www.hks-power.co.jp/en/product_db/exhaust/db/36571
