This combo performed exactly as stated, it gave a clean crisp throttle response, and excellent pull through the mid and into the top. This thing pulls so much better through the mid range that it has transformed our starts. If we aren't getting the hole shot, we are fighting for it. The only reason I didn't give 5 stars is the pipe is too thin, gets dents very easy. Ours didn't make it through one weekend of racing before denting up. I don't believe we have lost any performance from the dents, but just saying.

Put this on my yz 125, very easy to install. Run better and I can feel the difference in power. This is a great product and I highly recommend it. The shipping wasn't that great though. The box was all torn up and took two weeks.
makes my cr250 chime, and looks dern good.
I havent really had a chance to really see what this new exhaust is capable of. I installed it along with a Trailtech lightweight flywheel on my 2006 KTM 300 XC-W and for the 5 minute ride i took the bike seemed much snappier and layed down rubber through the end of second gear.
Perfect! wish they were impervious to damage on my second set!
I have used this pipe on three of my bikes and the outcome is always the same. Really woke up my new yz250, a lot more pull up top.
This pipe does everything it claims to do. Huge increase in power and not to mention it looks extremely b/a. I have a walk around vid on youtube for the stock pipe and then after i put on this one
excellent power increase across entire power band pipe looks very good on bike pipe bolted on easily silencer a bit tough to bolt on -most likely bent subframe though-recommend pipe and silencer combo for best results
The combo works great together and it gives you that little extra kick that stock doesnt give you. Its not a huge power boost but you can for sure tell out on the track. It pulls and pulls, sounds great, looks great, and holds up pretty well. It didnt take long at all to put on. The chrome header is awesome and stays shiny with a little WD40 every once in a while.
I think FMF did apoor job on sealing the pipe to the cilynder.We replace the O rings every other ride. I called FMF and they would not give me a solution to the problem.As a father keeping 85's going for the next day racing they could have been more helpful, other than o well keep tearing down and replacing.
If you do more tight track riding than trails go with the shorty, if you like to do a mixture of both go with the powercore.
