B-Ware - Tuning exhaust AOA3 GEN2 - traces of installation and use available Features: - Adjustable AOA3 countercone with reflective plate (GEN2) - Update 2020 with reflective plate, wider power band and lower noise development - Resonance length freely selectable - high quality chrome - sanded weld seams - quiet, unobtrusive rear silencer - tuning manifold, 32mm outer diameter The AOA 3 2019 was developed by ZT-Tuning, to support the widest possible range of motors. With an adjustable position of the countercone, it is possible to adapt the motor characteristics to the respective motor or personal preferences. In addition, the laying has been optimized to avoid grinding or placing on a large sloping position. In the 2019 variant, the greatest attention was paid to series optics. This exhaust has no additional weld seams. The manifold is fastened by means of a standard retaining clamp. The overall length of the system is almost standard. In combination with the narrower laying, it is easily possible to continue using the original bracket. All of these points make it very difficult to distinguish this exhaust from a serial exhaust system. Note: What is an AOA3? AOA3 is an abbreviation for modified original exhaust. In addition to a modified rear silencer, the exhaust has a tuning manifold with an inner diameter of 29 mm. This exhaust is excellent for original and easily tuned engines. In contrast to a closed-cone resonance exhaust, this exhaust supports the cylinder charging over a wider speed range.
