The ASM Siren Circuit Exhaust is a completely new design approach than the S-Special series. It utilizes 5 individually hand made silencers and articulation forks to eliminate harmonic overtones in the 200~300Hz frequency band and specific rpm ranges for a truely pure sound. Designed to achieved a unique siren sound and comply with Japanese road regulations of 93db astonishingly without the use of glass wool mufflers. The absence glass wool packed mufflers and resonators dramatically increases the lifespan of the exhaust and prevents increase in volume and tone over time. The exhaust has a complete straight through design with no restrictive perforated core mufflers for smooth air flow. This incredibly complicated exhaust is completely hand made down to the internal structure of the silencers. The exhaust is designed to have a near stock volume at low rpms and partial throttle and gently open up as you increase revs at wide open throttle. The 60mm piping isn't designed for maximum power gains but rather better throttle response and a long lasting finely tuned sound.
