Good bang for your buck!
This full system really woke my bike up especially in the top end! The power delivery is smooth but packs a punch when you really lay into it. The pipe sounds deep and throaty and has an awsome look to it. It was a fair price and worth every penny in my opinion!

KTM 2020 excf
Fit the full system on a 2020 KTM 500 excf. Takes a bit to get everything to line up but it's possible. You will have to remove the fuel tank to get extra cable for the O2 sensor that is tied up below the tank.
