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

■Detailed Description
●Exhaust Pipe
The 4in2in1 collector system 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 collector play an important role in creating a sensuous and refined exhaust note.
STKM11A (carbon steel tube for machine structural purposes), which offers excellent tensile strength and fatigue resistance, has been selected as the material.
Each component undergoes a precise polishing process by skilled craftsmen, followed by multi-layer plating using advanced surface treatment technology, achieving both exceptional aesthetics and long-lasting weather resistance.
●Silencer
The φ67×300 silencer, which produces a unique and exhilarating racing sound, has a complete double-layer internal structure, allowing for maximum sound deadening with minimal exhaust resistance.
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 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 system consisting of a total of five parts: "four front exhaust pipes (from the engine to the collector)" and "one tail ASSY (including the silencer from the collector)".
●Installation Status
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, use the free flange (exhaust holder) included with this product.
