【RPM 2621Y-01 Full Exhaust Muffler RPM-67Racing Titanium φ67×300 CB400SF VTEC SPEC1/2/3 Public Road Legal Roku Nana Racing RPM】
■Product Description
The RPM-67Racing is an exhaust system born from approximately 300 meticulous handcrafted processes and TQC (Total Quality Control). It was launched in 1998 as an original muffler brand, a replica model of the F-TYPE, without significant changes to the appearance of the RPM-4in2in1 F-TYPE manufactured until 1989, or to the internal structure of the silencer, which is crucial for sound quality.

■Detailed Description
●Exhaust Pipe
The adopted 4in2in1 manifold system provides a higher exhaust synergy effect than the 4in1 manifold system for 4-cylinder engines, and significantly contributes to producing a high-quality sound.
The material used is steel (STKM11A mechanical structure carbon steel pipe). Each component is carefully polished by skilled craftsmen, then given a high-quality plating treatment to provide superior aesthetics and weather resistance.
●Silencer
The φ67×300 size silencer, which produces a unique, exhilarating racing sound, achieves maximum silencing effect with minimum exhaust resistance by having a completely double-layered internal structure.
Furthermore, its lightweight and compact body possesses high rigidity and excellent resistance to vibration under harsh operating conditions.
●Silencer Outer Cover Lineup
The outer cover material is available in the following three types:
・Aluminum alloy A6063S
・Stainless steel SUS304 / mirror finish
・Titanium TP270
●Component Parts
This is a full exhaust muffler consisting of a total of five parts: "four front exhaust pipes (from the engine to the collector section)" and "one tail ASSY (from the collector section including the silencer)."
●Installation
It is fixed to the vehicle body at two points: the engine exhaust port and the tail stay.
When installing at the engine exhaust port, the free flange (exhaust holder) included with this product is used.
※Exhaust gaskets are not included, so you will need to prepare them separately.
●About Silencer Structure Requirements
The RPM-4in2in1 F-TYPE allowed for the removal and installation of the inner silencer built into the silencer for race use or repair purposes. However, many users rode on public roads with the inner silencer removed, which resulted in an outcome contrary to the original intention. Therefore, RPM welds the inner silencer in place.
※Sound volume adjustment and back pressure adjustment are not possible in the new product shipping state.
