Show original supplier description
The use of mandrel-bent piping is key to achieving optimal exhaust flow. This precise bending technique ensures consistent pipe diameter throughout, minimizing restrictions and turbulence. The result is a smoother path for exhaust gases, which can contribute to improved engine performance and a more aggressive exhaust note. This particular exhaust system is crafted in a Japanese N1 style, characterized by its performance-oriented design. It features a substantial 4-inch exhaust tip and a 2.25-inch catback piping diameter, engineered to enhance exhaust scavenging and sound. The system is made entirely from stainless steel for durability and a premium appearance. Designed specifically for the Honda CRX from model years 1988 through 1991, this exhaust system fits all available trims. Installation is straightforward as it is a direct replacement for the factory unit, and it comes with necessary gaskets. Some sources mention an increase of up to 15 hp, though this is a manufacturer claim.
