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

■Detailed Description
●Exhaust Pipe
The adopted 4in2in1 manifold system provides higher exhaust synergy than a 4in1 manifold system for 4-cylinder engines and contributes significantly to producing a high-quality sound.
The material used is steel (STKM11A mechanical structure carbon steel pipe). Each component is carefully polished by craftsmen and then subjected to a high-quality plating process, providing excellent aesthetics and weather resistance.
●Silencer
The φ67×300 size silencer, which produces a uniquely exhilarating racing sound, achieves maximum sound deadening with minimum exhaust resistance by having a complete double-layer internal structure.
Furthermore, its lightweight and compact body has 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 (from the collector including the silencer).
●Installation
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.
*Exhaust gaskets are not included, so you will need to prepare them separately.
