■Product Description
The RPM-4in2in1 is an exhaust system born from meticulous handcrafting through approximately 300 steps and TQC (Total Quality Control), and has been a popular original muffler brand among many users since its inception in 1978.

■Detailed Description
●Exhaust Pipe
The adopted 4-in-2-in-1 manifold system 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 a crucial role in creating a sensuous and refined exhaust note.
The material selected is STKM11A (carbon steel tube for machine structural purposes), which offers excellent tensile strength and fatigue resistance.
Each component, meticulously polished by skilled craftsmen, undergoes multi-layer plating using advanced surface treatment technology, achieving both exceptional aesthetics and long-term weather resistance.
●Silencer
The φ67×300 silencer, which produces a uniquely 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 3 types:
・Aluminum Alloy A6063S
・Stainless Steel SUS304 / Mirror Finish
・Titanium TP270
●Component Parts
This is a full exhaust system 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)".
●Mounting Condition
It is fixed to the vehicle at two points: the engine exhaust port and the tail stay.
When mounting to the engine exhaust port, use the free flange (exhaust holder) included with this product.
