KTM

This Akrapovič silencer has been conceived especially for enduro riders who are looking for the best exhaust system available on the aftermarket and who know how optimum power development can best be achieved on the enduro course or in offroad use. The hexagonal silencer is a perfect match for the sharp lines of the KTM. With removable noise reduction insert. Installation only possible with original header. Can also be fitted in combination with factory headers on 350/400/450/500/530 EXC.
