For the most part, yes. We build our mufflers to be fully interchangeable between all of our products, stock components and other aftermarket companies’ products. This way you don't have to worry about something not fitting down the road.
There are a few instances where our muffler will only fit our header, but that's because we weren't able to get the gains/fit we wanted with out making it an FMF only version.
Some KTM’s slip-ons do not allow for an additional header to be added. We recommend you call one of our customer service representatives at 310-631-4363 before you make any purchases.
