I have tried every major name brand exhaust system on the market and this will alway be the one I choose from now on. I know that every time I install a new pipe from fmf is will be a direct bolt on application with now issues. The head and mud pipe seal is always correct and rarely ever has any exhaust gasses or oils leak out causing a mess and loss of power. Significant impact will sent the pipe but day to day durability is on point.

My pipe did not come with the rubber rings or springs
Made a noticeable bottom end power increase, pleased with the performance and would recommend this product.
On the appearance side it could be better. The welds aren't very good and they never got touched up or finished so the welds are already rrusted. There was also a very minor dent but I am more concerned with performance not appearance. Overall good product.
Easy to install with awesome performance and no jetting change
Amazing exhaust. Easy to install
Bought this pipe as a up grade over the stock one. Like the increase in power and the sound is nice and it fits well also. Very nice product.
Bought this for a good friends son. He rides almost all off road, hare scrambles, and enduros and even a GNCC. He was excited!! He said it was a total improvement over stock . Fit and finnish COOL! FMF makes quality stuff!
Installed on an 05 RM250 Race Bike that previously had the FMF Fatty and noticed an immediate improved in throttle response, and better top end. Not to mention the sound of the bike is much more crisp. Sounded and performed better than a PC on an identical 05RM250. Also purchased a PowerCore II Titanium silencer to complement the pipe. Bike dropped about three pounds over the old Fatty & Silencer. Be sure to cover pipe in Pam during rides. Post ride; clean then lubricate with WD40 as it is the works finish and will rust.
This pipe is so worth the money. 22% HP gain in this bike. 2.5hp and it hits hard. Turn your sr into an sxs with this pipe. They do not do anything different at the factory. Go from an 85 to a 90 main jet and let it rip. Evan is now getting the holeshots on the cobra's
The exhaust made a good power increase throughout the whole rev range only problem is that it is prone to rust unless looked after exceptionally carefully.
added lots of power to my ktm 125. power was more noticable in bottom to mid range pull. Bought with a jd jet kit which helped a ton
love the pipe and its almost worth your money but if u put your bike away muddy or dirty the it will rust and it will not come off with wd40.
it wont look the best if u dont wash it after your done riding.
I have this pipe on both my 05' CR125 and 07' CR250. For 125's you can expect a healthy increase in midrange pull with a little bit more over rev. Throttle response is also improved slightly if jetted correctly. For a 250 you can expect to see an increase in the bottom through midrange with a little more over rev. Where this pipe stands out is that it delivers a healthy amount of power just about everywhere but in a useable nature. Fit and bolt on is spot on and both pipes were matted with a shorty silencer. I gave the durability a 4 because as with any "works" finish pipe you have to rub it down with wd40 and give it a sos pad scrub once in a while to keep away the rust. Overall great pipe from a company keeping 2 strokes alive.
FMF makes a great product. Adds more usable power where needed and is much stonger than stock. I have had a few procircuit pipes on my yz250 and loved the power but the are not near as tough as these.
this does exacctly wat it says i just got it for my 2012 ktm125sx it gives a huge power inccrease
This pipe sounds great and has a lot of power! I plan on buying this for all of my other dirtbikes as well! :)
