[Product Features and Recommended Points]

●Optimal for City Driving with Improved Quietness Kakimoto Racing’s inner silencer solves common concerns when using stock or sports mufflers, such as “excessively loud exhaust sound” or being cautious during nighttime or in residential areas. It can be easily installed and removed, allowing “volume control” according to your preference. Highly recommended for those who prefer quieter driving, are considerate of neighbors, or frequently drive in residential areas.

●Reliable Design Compatible with Stock Mufflers Kakimoto Racing mufflers are originally designed to meet road-use certification (JASMA certified) without an inner silencer. However, by providing a mounting hole at the tail for the inner silencer, it addresses requests such as “wanting a quieter muffler” or “adjusting the volume depending on the day’s mood.”

●Compatible Mufflers and Fitment This product (model number: RIS002) has a tail outer diameter of 89.1φ, overall length of 130mm, and inner diameter of 38.1φ. It is especially compatible with the following series: Regu.06 & R / Regu.92‑Z / Regu.96‑R. Vehicles equipped with these mufflers can easily switch to a “quiet specification.”

●Ease of Use and Convenience Installing and removing the inner silencer is extremely simple. No special tools or complicated procedures are required, making “volume on/off” very convenient. If needed, commercially available tools such as “Torutorukun” can make removal and installation smoother.

●Flexible Sound Adjustment as a Pure Tuning Part Designed not for complete silencing but for “moderate sound reduction.” This allows users to maintain exhaust efficiency and muffler sound balance while improving ride comfort and city-driving usability.

[Recommended For]

- People concerned about loud muffler noise disturbing neighbors

- Those who prioritize quietness during city driving, nighttime, or in residential areas

- People who want to enjoy a moderate muffler sound rather than an extreme “loud” sound

- Users who already have a compatible Kakimoto Racing muffler and want to adjust volume depending on mood or usage

- People who want to easily upgrade to a “quiet specification” without hassle

[Summary] The Kakimoto Racing Inner Silencer 89.1φ 130mm 80mm RIS002 is a highly practical and user-friendly “volume adjustment part” for those concerned about muffler noise. If your muffler is compatible, it can be easily installed without tools, making city driving and residential area use much more comfortable. Rather than purely seeking silence, it perfectly balances “moderate sound + road comfort.” For users already equipped with a Kakimoto Racing muffler, installing this inner silencer is the fastest way to try a quiet specification.
