【RPM 2059-01 Full Exhaust Muffler RPM-4in2in1 Aluminum φ77×300 CB400F Road Legal JMCA Certified 4-2-1 Motorcycle RPM】
■Product Description
The RPM-4in2in1 is an exhaust system born from approximately 300 meticulous handcrafting processes and TQC (Total Quality Control), and has been a popular original muffler brand since its inception in 1978.

■Detailed Description
●Exhaust Pipe
The adopted 4-in-2-in-1 manifold system has a higher exhaust synergistic effect than a 4-in-1 manifold system in a 4-cylinder engine, and is also one of the elements that produces a high-quality sound.
The material used is steel (STKM11A mechanical structure carbon steel pipe). Each component is carefully polished by skilled craftsmen, then subjected to high-quality plating to provide both high aesthetic appeal and weather resistance.
●Silencer
The φ77×300 size silencer has a straight-through structure.
While achieving high exhaust efficiency, it incorporates unique sound-absorbing glass wool to provide excellent quietness.
The outer cover material is available in the following two types:
・Aluminum Alloy A6063S
・Stainless Steel SUS304/Mirror Finish
●Component Configuration
This is a full exhaust muffler consisting of a total of five parts: "four front exhaust pipes (from the engine to the manifold)" and "one tail ASSY (including the manifold and silencer)".
●Mounting Condition
It is fixed to the vehicle at two points: the engine exhaust port and the tail stay.
When installing at the engine exhaust port, use the included RPM free flange (exhaust holder).
※Exhaust gaskets are not included, so you will need to prepare them separately.
●Silencer Structure Requirements
Sound and back pressure adjustments are not possible in the new factory-shipped state.
