■Detailed Description
●Exhaust Pipe
The adopted 4-in-2-in-1 manifold system offers higher exhaust synergy than a 4-in-1 system for 4-cylinder engines, and significantly contributes to producing a high-quality sound.
The material used is steel (STKM11A mechanical structure carbon steel pipe). Each component is meticulously polished by craftsmen, then undergoes high-quality plating to provide excellent aesthetics and weather resistance.
●Silencer
The lightweight and compact body, sized φ67x300, boasts high rigidity and excellent resistance to vibration under harsh operating conditions. It also enhances the overall silhouette when installed 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.
It offers higher quietness performance compared to the RPM-67Racing.
●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 Configuration
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)."
●Installation
