It is an original muffler brand launched in 1998 as an F-TYPE replica model, retaining the appearance of the RPM-4in2in1 F-TYPE manufactured until 1989, and largely preserving the internal structure of the silencer, which is crucial for sound quality.\u003c\/p\u003e\n\n\u003cp\u003e■Detailed Description\n\u003cbr\u003e●Exhaust Pipe\n\u003cbr\u003eThe adopted 4in2in1 manifold system provides higher exhaust synergy than a 4in1 manifold system for 4-cylinder engines, and significantly contributes to generating a high-quality sound.\n\u003cbr\u003eThe material used is steel (STKM11A mechanical structural carbon steel pipe). Each component is meticulously polished by artisans before being subjected to high-quality plating, providing excellent aesthetics and weather resistance.\n\u003cbr\u003e●Silencer\n\u003cbr\u003eThe φ67x300 silencer, which produces a unique and exhilarating racing sound, achieves maximum silencing effect with minimum exhaust resistance by having a completely double-layered internal structure.\n\u003cbr\u003eFurthermore, its lightweight and compact body possesses high rigidity and excellent resistance to vibrations under harsh operating conditions.\n\u003cbr\u003e●Silencer Outer Cover Lineup\n\u003cbr\u003eThe outer cover material comes in the following three types:\n\u003cbr\u003e・Aluminum alloy A6063S\n\u003cbr\u003e・Stainless steel SUS304\/mirror finish\n\u003cbr\u003e・Titanium TP270\n\u003cbr\u003e●Component Configuration\n\u003cbr\u003eThis is a full exhaust muffler consisting of a total of five parts: \"four front exhaust pipes (from the engine to the collector)\" and \"one tail ASSY (from the collector including the silencer).\"\n\u003cbr\u003e●Installation Status\n\u003cbr\u003eIt is fixed to the vehicle at two points: the engine exhaust port and the tail stay.\n\u003cbr\u003eWhen installing at the engine exhaust port, use a genuine Kawasaki free flange (exhaust holder).\n\u003cbr\u003e※Exhaust gaskets and genuine Kawasaki free flanges (exhaust holders) are not included. You will need to prepare them separately.\n\u003cbr\u003e※The \"split collar\" used when installing the genuine muffler is not required when installing this product.\n\u003cbr\u003e●About Silencer Structure Requirements\n\u003cbr\u003eThe RPM-4in2in1 F-TYPE allowed for the attachment and detachment of the inner silencer built into the silencer for race use and repair purposes. However, many users on public roads ran with the inner silencer removed, which was contrary to the original intention. Therefore, RPM has welded the inner silencer in place.\n\u003cbr\u003e※Sound volume and back pressure cannot be adjusted in the new product shipping state.\u003c\/p\u003e\n\n\u003cp\u003e■Compatible Models\n\u003cbr\u003eKawasaki\n\u003cbr\u003eZEPHYR400 (All model years)\n\u003cbr\u003eZEPHYR400 Kai (-2000)\u003c\/p\u003e\n\n\u003cp\u003e■Specifications\n\u003cbr\u003eSilencer Cover: Stainless steel\n\u003cbr\u003eExhaust Pipe: Steel plating\n\u003cbr\u003eFitting Type: Full exhaust\n\u003cbr\u003eSilencer Size: φ67x300\n\u003cbr\u003eOil Change: 〇\n\u003cbr\u003eOil Filter Change: ×\n\u003cbr\u003eTandem: 〇\n\u003cbr\u003eCenter Stand: ×\n\u003cbr\u003eRoad Legal: 〇\n\u003cbr\u003eCatalytic Converter: None\n\u003cbr\u003eProximity Exhaust Noise Level: 99db\u003c\/p\u003e\n\n\u003cp\u003e■Notes\n\u003cbr\u003e※This is for the muffler only.
