■Product Description
The RPM-4in2in1 is an exhaust system born from approximately 300 meticulous handcrafted processes and TQC (Total Quality Control), and is an original muffler brand that has been loved by many users since its inception in 1978.

■Detailed Description
●Exhaust Pipe
The 4-in-2-in-1 manifold adopted suppresses exhaust interference unique to 4-cylinder engines, and in synergy with the precise exhaust port design, achieves excellent exhaust efficiency across all RPM ranges.
In addition, its unique pipe length and optimized manifold play an important role in creating a sensuous and refined exhaust note.
STKM11A (carbon steel pipes for machine structural purposes), which offers excellent tensile strength and fatigue resistance, has been selected as the material.
Each component, having undergone a precise polishing process by skilled craftsmen, is treated with multi-layer plating using advanced surface treatment technology, achieving both exceptional aesthetics and long-term weather resistance.
●Silencer
The φ67×300 size silencer, which produces a uniquely 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 vibrations under harsh operating conditions.
●Silencer Outer Cover Lineup
The outer cover materials are available in the following 3 types:
・Aluminum alloy A6063S
・Stainless steel SUS304/mirror finish
・Titanium TP270
●Component Parts
This is a full exhaust muffler consisting of a total of 5 parts: 4 front exhaust pipes (from the engine to the manifold) and 1 tail ASSY (from the manifold including the silencer).
