Full Exhaust Muffler RPM-67Racing Aluminum φ67x300 ZZR400

【RPM 1638-01 Full Exhaust System RPM-67Racing Aluminum φ67×300 ZZR400 Road Legal ROKUNANA Racing Motorcycle RPM】
■Product Description
The RPM-67Racing is an exhaust system born from meticulous handcraftsmanship involving 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 4-in-2-in-1 manifold system offers higher exhaust synergy than a 4-in-1 manifold system for 4-cylinder engines and significantly contributes to producing a high-quality sound.
The material used is steel (STKM11A carbon steel pipes for machine structural purposes). Each part is carefully polished by skilled artisans before undergoing high-quality plating, which provides excellent aesthetics and weather resistance.
●Silencer
The stylish φ67×300 silencer achieves maximum sound dampening with minimum exhaust resistance by having a completely double-layered internal structure.
Furthermore, this lightweight and compact muffler possesses high rigidity, offering excellent resistance to vibrations under harsh operating conditions. Another feature is how it enhances the overall silhouette when mounted on the vehicle.
Inheriting the internal structure of the silencer used in the RPM-4in2in1 F-TYPE, it produces a deep bass sound at low RPMs and a unique, exhilarating racing sound at high RPMs.
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 manifold)" and "one tailpipe ASSY (from the manifold including the silencer)."
●Mounting Condition
It is fixed to the vehicle at two points: the engine exhaust port and the tail stay.
When installing at the engine exhaust port, the included RPM free flange (exhaust holder) is used.
※Exhaust gaskets are not included, so you will need to prepare them separately.
