Both SS400 and ST-OVAL have high quietness like stock and high quality sound with pleasant bass.
It's as quiet as stock at low speeds and idling, even in residential areas.
In addition, when accelerating, a moderate bass sound will be heard, further enhancing the fun riding.
The inside of the silencer also uses BEAMS' original bulkhead structure, so there is no need for any troublesome settings.
You can enjoy it with a natural feeling like the stock one.
This exhaust is especially recommended for those who think that a noisy exhaust is not good for them.
Original bulkhead structure has successfully balanced the conflicting requirements of pleasant sound, quietness, and easy-to-handle mid to low speed torque without sacrificing high speed range.
No additional processing is required for installation, and you can enjoy customization easily by pursuing the standard convenience and durability.
In addition to the standard baffle [except JMCA types], the volume and output characteristics can be adjusted in three stages by simply replacing the baffle with the optional semi-racing baffle.
[standard volume]
Less than 83dB (when stock baffle is installed)
Less than 90dB (when semi-racing baffle is installed)
Less than 94dB (when baffle is not installed)
