Description
Crafted for Precision. Tuned for Emotion.
Born from the collaboration between 『BFM Performance』 and 『Frequency Intelligent Exhaust』,
This system redefines what a three-cylinder performance car can sound and feel like.
Engineered specifically for the GR Yaris, it blends 『Taiwanese carbon craftsmanship』 with 『FI’s signature valvetronic technology』,
creating a seamless union of design precision and sound control.
**Precision Engineering**
Constructed from 「T304 stainless steel」—one grade below medical quality—the entire system is 3D-scanned from the OEM layout to ensure a 100% bolt-on installation, requiring no cutting or chassis modification.
Each weld is hand-crafted using TIG welding, ensuring strength, consistency, and the signature Fi finish.
**Dual Personality Performance**
The valvetronic system allows drivers to control exhaust flow, tone, and back pressure at will.
『Valve closed』: refined, composed, and road-friendly.
『Valve open』:raw, aggressive, and race-ready.
Paired with a full turbo-back setup (mid-pipe + high-flow downpipe), performance gains can reach 5–10% horsepower, unleashing the full potential of the GR Yaris.
**Seamless Control**
Control modes are switchable via the 『remote controller』, or for selected models, integrated with OEM drive modes.
The Fi Control Box offers intelligent automatic valve operation, adjusting in real time to driving behavior for an adaptive exhaust experience.
Where Sound Meets Craft
This isn’t just an exhaust, it’s the voice of BFM’s design precision meeting FI’s acoustic intelligence.
Every tone, every weld, every detail embodies the shared belief in 『performance as an art form』.
