Akrapovic Decibel Reducer Insert (V-TUV309) — An exhaust accessory designed for those who want to control the output volume without compromising the look of the exhaust. This insert, also known as a decibel reducer or "dB killer", fits into the silencer pipe to reduce the noise level and make the sound more contained during urban rides or to comply with certain local restrictions.
Easy to install for a knowledgeable motorcycle DIYer or preparer, this insert fits Akrapovic-compatible silencers and outlets designed for this type of accessory. It allows for sound modulation without altering the aesthetics of the exhaust and maintains the original exhaust alignment. Ideal for owners of high-performance sports bikes — particularly the Kawasaki ZX-10 R/RR 2025 series — looking for a practical and reversible attenuation option.
