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

■Detailed Description
●Exhaust Pipe
The 4in2in1 manifold system adopted offers a higher exhaust synergy effect than the 4in1 manifold system for 4-cylinder engines, and also contributes significantly to producing a high-quality sound.
The material used is steel (STKM11A carbon steel pipes for machine structural purposes). Each component is carefully polished by skilled craftsmen, then undergoes high-quality plating to provide excellent aesthetics and weather resistance.
●Silencer
The lightweight and compact φ67x300 body has high rigidity and excellent resistance to vibrations under harsh operating conditions. It also enhances the overall silhouette when mounted on the vehicle.
Equipped with a uniquely developed silencer, it produces a deep sound at low RPMs and a unique, exhilarating racing sound at high RPMs.
Compared to the RPM-67Racing, it offers even higher quietness.
●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 Composition
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 to 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.
