Full Exhaust System RPM-67Racing Stainless φ67x300 Zephyr 400/Kai

【RPM 1630S-01 Full Exhaust Muffler RPM-67Racing Stainless φ67x300 ZEPHYR400/Kai Road Legal Rokunana Racing Bike RPM】
■Product Description
The RPM-67Racing is an exhaust system born from meticulous handcrafting through approximately 300 processes and TQC (Total Quality Control). It is an original muffler brand launched in 1998 as an F-TYPE replica model, retaining the appearance of the RPM-4in2in1 F-TYPE manufactured until 1989, and largely preserving the internal structure of the silencer, which is crucial for sound quality.

■Detailed Description
●Exhaust Pipe
The adopted 4in2in1 manifold system provides higher exhaust synergy than a 4in1 manifold system for 4-cylinder engines, and significantly contributes to generating a high-quality sound.
The material used is steel (STKM11A mechanical structural carbon steel pipe). Each component is meticulously polished by artisans before being subjected to high-quality plating, providing excellent aesthetics and weather resistance.
●Silencer
The φ67x300 silencer, which produces a unique and exhilarating racing sound, achieves maximum silencing effect with minimum exhaust resistance by having a completely double-layered internal structure.
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 comes in the following three types:
・Aluminum alloy A6063S
・Stainless steel SUS304/mirror finish
・Titanium TP270
●Component Configuration
This is a full exhaust muffler 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 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, use a genuine Kawasaki free flange (exhaust holder).
※Exhaust gaskets and genuine Kawasaki free flanges (exhaust holders) are not included. You will need to prepare them separately.
※The "split collar" used when installing the genuine muffler is not required when installing this product.
●About Silencer Structure Requirements
The RPM-4in2in1 F-TYPE allowed for the attachment and detachment of the inner silencer built into the silencer for race use and repair purposes. However, many users on public roads ran with the inner silencer removed, which was contrary to the original intention. Therefore, RPM has welded the inner silencer in place.
※Sound volume and back pressure cannot be adjusted in the new product shipping state.
