【RPM 2055-01 Full Exhaust System Muffler RPM-4in2in1 Aluminum φ67×300 CB400F Street Legal 4-2-1 Motorcycle RPM】
■Product Description
The RPM-4in2in1 is an exhaust system born from approximately 300 meticulous hand-crafting processes and TQC (Total Quality Control). Since its inception in 1978, it has been a popular original muffler brand cherished by many users to this day.

■Detailed Description
The exhaust pipe, from the engine exhaust port to just before the silencer, is made of steel.
The exhaust pipe, carefully polished over dozens of steps by craftsmen, is copper-plated, nickel-plated, and then finally hard chrome-plated.
This creates the unique luster characteristic of steel plating, which then changes to a distinctive burnished color when heated by the exhaust.
Furthermore, the exhaust note produced by steel has a uniquely high-quality sound.
The "4in2in1 manifold," created using a proprietary manufacturing method, was developed over a long period of conceptualization.
The adoption of this manifold system achieves impressive high torque characteristics in the mid-to-low speed range.
This full exhaust system produces an exhilarating racing sound while keeping the volume within regulated limits.
