【RPM 3022S-01 Full Exhaust System RPM-4in2in1 Stainless Steel φ93×390 XJR400R Street 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). It is an original muffler brand that has been highly favored by many users since its inception in 1978.

■Detailed Description
●Exhaust Pipe
The adopted 4-into-2-into-1 manifold system suppresses the exhaust interference unique to 4-cylinder engines. This, combined with a precise exhaust port design, synergistically achieves excellent exhaust efficiency across all RPM ranges.
Furthermore, its unique pipe length and optimized collector play a crucial role in creating a sensual and refined exhaust note.
The material selected is STKM11A (carbon steel mechanical tubing), which offers excellent tensile strength and fatigue resistance.
Each component, having undergone a precise polishing process by skilled craftsmen, is then treated with multi-layer plating using advanced surface treatment technology, achieving both exceptional aesthetics and long-lasting weather resistance.
●Silencer
The large-capacity φ93×390 silencer achieves a high-level balance between two conflicting performances: advanced exhaust efficiency and outstanding quietness.
Notably, its uniquely developed internal structure creates an innovative exhaust note that pleasantly stimulates the auditory sense across the entire range from low to high RPMs.
●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 Structure
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 tailpipe ASSY (including the collector to the silencer)."
●Mounting Condition
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, the included vehicle-specific free flange (exhaust holder) is used.
※Exhaust gaskets are not included, so you will need to prepare them separately.
