【RPM 2021Y-01 Full Exhaust System RPM-4in2in1 Titanium φ67×300 CB400SF VTEC SPEC1/2/3 Road Legal 4-2-1 Motorcycle RPM】
■Product Description
The RPM-4in2in1 is an exhaust system born from approximately 300 meticulous hand-made processes and TQC (Total Quality Control). Since its inception in 1978, it has been an original muffler brand loved by many users.

■Detailed Description
●Exhaust Pipe
The 4-in-2-in-1 manifold adopted provides a higher exhaust synergistic effect in 4-cylinder engines than a 4-in-1 manifold, and greatly contributes to producing a high-quality sound.
The material used is steel (STKM11A carbon steel pipes for mechanical structures). Each part is carefully polished by skilled craftsmen, and then undergoes high-quality plating to give it high aesthetic appeal and weather resistance.
●Silencer
The lightweight and compact φ67×300 sized body has high rigidity, making it not only excellent in vibration resistance under harsh conditions, but also characterized by its ability to beautifully shape the overall silhouette when mounted on the vehicle.
Equipped with a uniquely developed silencer, it produces a deep bass sound at low RPMs and a unique, exhilarating racing sound at high RPMs.
It offers higher sound suppression performance compared to the RPM-67Racing.
●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 Structure
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 tail 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, use the free flange (exhaust holder) included with this product.
※Exhaust gaskets are not included, so you will need to prepare them separately.
