          Rated 4 out of 5 by from Looks good, but came all scratched up. Looks and sounds good but the part nearest to the head was sorta scratched up, not a huge deal for me as I'll probably wrap it. It's also way quieter than I expected which I like, but if you're going for a loud exhaust you may not want that.

          Rated 4 out of 5 by from Nice n' strong Now although this bike says it adds "upto 10% power" you wont feel it, but with that being said, it is built extremely well and the welds are flawless, the header is nice and solid and a bit on the heavy side but dents will be less likely, shipping was extremely fast and the header fit with 0 issues

          Rated 5 out of 5 by from Should come as a factory part I installed the FMF PowerBomb with the FMF Q4 and FMF EFI Programmer on my WR250X and noticed a nice increase in power/responsiveness.

          Rated 4 out of 5 by from Happy so far So I've only done one ride on this pipe so far. As far as I can tell at this point the power delivery was very smooth and there was no lack of it. Having said that, I haven't exactly had the bike on a dyno either. Fitment was great but I'm not super impressed with the flange to secure to the head. It's a little flimsy and at the proper torque spec it flexed / bent more than I wanted to see. Over all I'm happy.

          Do I need to order gaskets for either end, engine or muffler? I don't want to reuse crush gasket!

          Does this fit stock  muffler/exhaust on a 2009 Kx250f ?

          Asked by: Wayne
          FMF only lists this header for use with FMF mufflers specifically

          Does this fit the stock muffler of a 2017 rmz250?

          Asked by: Rmz250
          It should. The FMF muffler’s are designed to slip on to the stock header and fit the FMF line of headers as well.  By process of elimination, I would say it will. You may have to alter the gasket that joins the two either trim or add but I doubt it. Hope this helps. Just an FYI, I would recommend replacing either the muffler before the header or both at the same time.
