A catalytic silencer that produces the refined, clear sound that is unique to Kakimoto Kai, which is particular about sound quality, and ensures a steady increase in power.

The genuine catalyst is the most important part when considering how to improve power response in exhaust tuning. How to treat this part also makes a big difference in sound quality. Kakimoto offers a wide range of catalyst tuning parts.

Catalytic Silencer / Center Pipe

The Kakimoto modified catalytic silencer and center pipe feature a straight structure to improve power response.
Furthermore, it is purposely made into a thin bullet-shaped muffler, and by providing a moderate silencer function, it absorbs the rustling and crackling sounds in the high-frequency range without losing power.
By installing a catalytic silencer and center pipe, the exhaust sound has been upgraded to a refreshing and clear sound quality.

Catalytic Straight

Although its noise reduction function is inferior to that of catalytic silencers, a straight type with excellent cost performance is also available for users who are looking for more power and torque.
