I have a FMF 4.1 slip on for sale. It has a dent in the under side of it where some one same into me in my first race. I still use it to this day, the dent does not affect performance what-so-ever. If you didn't know it was there you'd prob not really notice it. I did feel some power gain with the slip on and a nice sound too, not too loud, meets AMA requirements. Im just picky and dont like the dent so i got a new one. $240 plus shipping. I will get some pics up soon. These go for $400 on FMF web site

Is this the blue or natural one? Did you have to re-jet? Does it have the spark arrestor/screen?
Where are you located?
Thanks

It is the blue one. I did re-jet but i did the slip-on and carb work at the same time, so im not sure what to jet for the pipe. I just use JD jet kit and it works amazing. No spark arrestor/screen, but i believe they can be purchased. Im located in NY
