I installed the FMF Factory 4.1 RCT Titanium slip-on muffler for the 2011-2013 ktm 250 350 450 sxf on my 09 FE 450. It bolted right up. Mounting hanger tabs matched up perfectly. However it does not seat fully up to the stop on the mid pipe. It is about 1/4 inch short. There is plenty of overlap on the muffler and mid pipe so I dont see an issue with it not seating all the way up on the mid pipe. I used some hi-temp copper RTV on the joint. The muffler is not loud using the spark arrestor insert. It's actually quieter than I thought it would be. It came with a quiet core insert and I had planned on running but using only the SA insert it has a nice deep exhaust note that is not obnoxious at all.
