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

■Detailed Description
●Exhaust Pipe
The 4-2-1 exhaust manifold system adopted in this product suppresses exhaust interference peculiar to 4-cylinder engines and exhibits a more advanced exhaust pulsation effect compared to the 4-1 manifold system, maximizing the engine's potential and creating sophisticated exhaust sound.
The material selected is carbon steel pipes for machine structural purposes (STKM11A).
After precise polishing by skilled craftsmen, plating with advanced surface treatment technology is applied, achieving both outstanding aesthetics and weather resistance.
●Silencer
The refined and compact form with a diameter of 77mm and a total length of 300mm creates an outstanding sense of unity with the vehicle, elevating its overall appearance to be more elegant.
Notably, the thoroughly optimized internal structure minimizes exhaust resistance to the utmost while achieving unparalleled silencing performance.
The outer cover material is available in the following two types of materials:
・Aluminum alloy A6063S
・Stainless steel SUS304/mirror finish
●Component Configuration
This is a full exhaust muffler consisting of a total of five parts: "four front exhaust pipes (from the engine to the manifold)" and "one tail ASSY (from the manifold including the silencer)".
●Installation Status
It is fixed to the vehicle at two points: the engine exhaust port and the tail stay.
When installing at the engine exhaust port, an RPM original free flange (exhaust holder) is used.
*Exhaust gaskets are not included, so you will need to prepare them separately.
