It was launched in 1998 as an F-TYPE replica model, retaining the appearance of the RPM-4in2in1 F-TYPE manufactured until 1989 and making no significant changes to the internal structure of the silencer, which is crucial for sound quality. It is an original muffler brand. \u003c\/p\u003e\n\n\u003cp\u003e■Detailed Description\n\u003cbr\u003e●Exhaust Pipe\n\u003cbr\u003eThe adopted 4-into-2-into-1 merge system offers higher exhaust synergy in 4-cylinder engines than the 4-into-1 system, and contributes greatly to producing a high-quality sound.\n\u003cbr\u003eThe material used is steel (STKM11A carbon steel pipes for mechanical structures). Each part is carefully polished by craftsmen before undergoing high-quality plating, providing excellent aesthetic appeal and weather resistance.\n\u003cbr\u003e●Silencer\n\u003cbr\u003eThe φ67×300 silencer, which produces a unique and exhilarating racing sound, achieves maximum silencing effect with minimum exhaust resistance by having a complete double-layer 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 Parts\n\u003cbr\u003eThis is a full exhaust system consisting of a total of five parts: \"four front exhaust pipes (from the engine to the merge collector)\" and \"one tail ASSY (from the merge collector, including the silencer)\".\n\u003cbr\u003e●Mounting Condition\n\u003cbr\u003eIt is secured to the vehicle at two points: the engine exhaust port and the tail stay.\n\u003cbr\u003eWhen attaching to 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 prepare 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 rode 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 volume adjustment and back pressure adjustment are not possible in the new factory-shipped condition. \u003c\/p\u003e\n\n\u003cp\u003e■Compatible Models\n\u003cbr\u003eHONDA\n\u003cbr\u003eCB400SF STD (NC31)\n\u003cbr\u003e※Not compatible with Ver.R and Ver.S\u003c\/p\u003e\n\n\u003cp\u003e■Specifications\n\u003cbr\u003eSilencer Cover: Titanium\n\u003cbr\u003eExhaust Pipe: Steel Plated\n\u003cbr\u003eFitting Type: Full Exhaust\n\u003cbr\u003eSilencer Size: φ67×300\n\u003cbr\u003eOil Change: 〇\n\u003cbr\u003eOil Filter Change: ×\n\u003cbr\u003eTandem: 〇\n\u003cbr\u003eCenter Stand: ×\n\u003cbr\u003eStreet Legal: 〇\n\u003cbr\u003eProximity Exhaust Noise Value: 99db\u003c\/p\u003e\n\n\u003cp\u003e■Notes\n\u003cbr\u003e※Only the muffler is for sale.
