Here is a two-part collection where in the first video, Dave at Dynobike talks us through installing an Akrapovic Decat System onto a 2022 Aprilia Tuono 1100.
In the second video, Dave demonstrates the differences in terms of power and torque at peak and throughout the rpm range between the stock Aprilia Tuono 1100 exhaust, Akrapovic Decat Exhaust System, and also a Full Akrapovic Exhaust System.
For best results, a Flash tune or a custom dyno tune is recommended.
You can find both Akrapovic exhaust systems via the below links as well as ECU flash and Custom Tune products.
