Hey everyone, I have a 2009 450XC that I want to get a slip-on for. I am basically a weekend warrior and only do a few races a year. Before everyone says go with the KTM Bill pipe I just want to state that I am just interested in a slip-on silencer. I do respect the KTM Bill pipe and I know it’s proven to produce very good gains over any aftermarket pipe on the market, however I feel for my use of the quad a slip-on with the stock header will do just fine for me, for now.


I am looking for any information I can find on the KTM/FMF silencer (the black can). I know the stock XC canister is pretty choked up from the factory. What kind of gains can be found with this slip on? To me it looks like it has the same design as the FMF Powercore 4 (same price too), just with a different exterior look. I've also read on this forum that it has the same power as the FMF Factory 4.1, however I don't know if this is true. If anyone can help me piece any information together that would be great. Thank you.
