Hello fellow riders :).
For background I am a Saturday and Sunday warrior. Not a racer just a intense rider. I ride a 2011 Ds450X MX. Aside dorm the slip on Motoworks SR4 it is stock.
I am considering upgrading my air box lid to a EHS Performance lid mod, a BCS Hi Flow ring and the K&N...
Have a 08 ds450x and I am looking for the best exhaust that works with it. I am looking at FMF but I just want to if there is any exhaust and programmer combos that work really well with the ds.
