Great product
Put it on a Kim 300 tpi and the difference between stock and this pipe is crazy, power delivery is smoothed right out and more responsive, like riding a totally different bike.

This Pipes Ugly, especially in comparison to the Pro Circuit it replaced; But it's solid.

Quality has gone downhill
I've run FMF fatty's on a few of my YZ250s over the year. Unfortunately quality has gone downhill with my latest one. Bought 2 weeks ago, have about 5-6 hours on the pipe. No crashes, tipovers, etc, but the FMF logo fell off, the spot welds broke right off the badging. Pipe still works well and is always a decent replacement on a YZ250.

Pipe adds low to mid power. Noticeable
Had to bend pipe as angle was off to slide into silencer without rubbing on frame. Bent output pipe about 3/8 to avoid pipe rubbing on frame.
Very surprised I had to bend to make it fit properly
