The performance of the Slip-On Line exhausts can be further enhanced by the addition of the odd bends. When this beautifully finished cornering system is added to a Slip-On Line exhaust for the Z900, the muffler turns into a complete racing system and increases power for even more fun. The addition of the bends will also improve the sound of the exhaust, giving it a sharper racing tone. The bends are therefore not EU approved.
You save 4.4kg with the cornering system compared to the original system.
Akrapovic recommends that the ECU mapping be adjusted.
