well made fit good looks like will take a beating
FMF has usually been top notch stuff for me, but I am kind of disappointed with the quality of the pipe. The welds are horrible on all of the seams. Lots of undercut and they didn't even bother cleaning off the spatter/ bb's. Very frustrating for the amount of money they charge. The quality control is non- existent. As far as performance I cannot rate it until I actually go ride.
Looks good on my 2025 Beta 300 race edition and excellent quality
