【RPM 3022Y-01 Full Exhaust System RPM-4in2in1 Titanium 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), 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.
Furthermore, its unique pipe length and optimized manifold 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 precise polishing by skilled craftsmen, is then subjected to multi-layer plating using advanced surface treatment technology, achieving both outstanding aesthetics and long-term weather resistance.
●Silencer
The large-capacity φ93×390 silencer achieves a high-level balance between the conflicting performances of high exhaust efficiency and excellent 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 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 tailpipe ASSY (from the manifold including the silencer)".
●Mounting State
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 please prepare them separately.
