It is an original muffler brand launched in 1998 as an F-TYPE replica model, without making significant changes to the appearance of the RPM-4in2in1 F-TYPE, which was manufactured until 1989, or to 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 4-in-2-in-1 manifold system offers higher exhaust synergy than a 4-in-1 manifold system in a 4-cylinder engine, and significantly contributes to producing a high-quality sound.\n\u003cbr\u003eThe material used is steel (STKM11A mechanical structure carbon steel pipe). Each component is carefully polished by skilled craftsmen before undergoing a high-quality plating process, providing both excellent aesthetics and weather resistance.\n\u003cbr\u003e●Silencer\n\u003cbr\u003eThe φ67×300 silencer, which produces a unique and exhilarating racing sound, achieves maximum sound dampening with minimal 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 is available 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 5 parts: \"4 front exhaust pipes (from the engine to the collector)\" and \"1 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 the free flange (exhaust holder) included with this product.\n\u003cbr\u003e※Exhaust gaskets are not included, so you will need to purchase them separately.\n\u003cbr\u003e●About Silencer Structure Requirements\n\u003cbr\u003eThe RPM-4in2in1 F-TYPE allowed for the removal and attachment of the inner silencer built into the silencer for race use and repair purposes. However, many users would ride on public roads with the inner silencer removed, which went against the original intention. Therefore, RPM now welds the inner silencer in place.\n\u003cbr\u003e※Sound adjustment and back pressure adjustment are not possible in the new factory-shipped state.\u003c\/p\u003e\n\n\u003cp\u003e■Compatible Models\n\u003cbr\u003eHONDA\n\u003cbr\u003eCB400SF VTEC SPEC1\/2\/3 (NC39)\n\u003cbr\u003e※Not compatible with NC42\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: φ67×300\n\u003cbr\u003eOil change: 〇\n\u003cbr\u003eOil filter change: 〇\n\u003cbr\u003eTandem: 〇\n\u003cbr\u003eCenter stand: ×\n\u003cbr\u003eRoad legal: 〇\n\u003cbr\u003e※Excluding vehicles regulated by a close-proximity exhaust noise level of 94db\n\u003cbr\u003eClose-proximity exhaust noise level: 99db\u003c\/p\u003e\n\n\u003cp\u003e■Notes\n\u003cbr\u003e※Only the muffler is for sale.
