great pipe
iv had this pipe for about a year now and its the best pipe iv had, has some power gains in bottom , mid, and top end but not to much, only con is it kinda dents easy, i was going around a turn and my front tire washed out and it put about a 3.50-4 inch dent in it and i wasnt even going fast. its good for trail riding if you buy a pipe guard for it, overall its a great pipe

So sick! Pit bike must have!!!!
Everything you'd expect from FMF in a smaller package. A huge performance boost only 4 bolts away. Way sick!

The FMF Fatty made all the difference, all the way up through the power band. Just don't let it get to beat up. You will be able to tell the differece if you do.
