A Banshee must!

Bought these for my Banshee, much better improvement over the Fattys. Gained a little in the low end, arm ripping midrange hit and eye opening top end. They pull very hard on top. Very good power from these pipes. Had a little trouble fitting the pipe into the silencer but it was no big deal. Finish still looks great after 3 years. Another great product by FMF.

Un mached

I used to have a pro c on my yz85 and it was junk it bent too Easley. This pipe gives your bike more power and is tuff. One problem though is you have to mess with your jetting a little I think I use a 138 main jet and a 40 pilot jet and the clip all the way down.

got this for my rm 125 04 and installed it very nice i race and trail ride so its perfect pipe but if your all racing and not like trail or yard riding go fatty cause this pipe is made for everything fatty is strictly race.

Excellent Product

The SST fit great and the over all performance is great too. Although for racing I think the fatty would be the better choice.

Everything you'd expect

Purchased for an 05 YZ250. Nice, broad power. Looks great. I paired it with the "long" powercore 2 and it seems good. A word on jetting. I went with the stock jetting on pilot and main and switched from the stock N3EJ to the N3EW needle as FMF suggests. But my fuel mix is Amsoil oil and race fuel @50:1. So at the recomended 4th clip setting, it was too rich. The 2nd clip is perfect and she just rips. Lots of over rev. You really will feel the needle change, yamaha went with it in the later model 250s for a reason.

Great exhaust

This is a great exhaust and fits very well on my CR 250. On this site when you look at the silencer it says only compatible with SST expansion chamber but when you look at Expansion chamber it does not say anything about needing the SST silencer. So when I ordered the chamber I then had to order the silencer the next week when I went to install on my bike with my old FMF shorty it did not match up with mounting holes. Now I know!

Best purchase ever

My 2005 RM 250 is a low-mid engine with decent low end and a really strong midrange. The one problem was that it totally flattens out in the upper RPM range. Keep reving the engine past the upper part of the midrange and all it does is make more noise. I get pulled big time at the end of straights by 450Fs. The bike just runs out of breath. I added a V-Force 3 reed, a 10oz Steahly flywheel weight to smooth the low/mid transition and a DSP Power Now Valve to both sides of the carb to improve low-end throttle response. All these helped improve the engine response but didn't help the upper end power. WOW. The FMF SST pipe and Powercore II silencer made a huge improvement. I hoped it would help a little. It helped a LOT. Maybe it's the combination of the pipe, reed and DSP parts that did it but the bike revs to the moon now. The low and mid-range are improved too. I highly recommend this pipe for an RM 250.

Fmf sst pipe

just bought it and installed it. it is an easy install, about 20 min for the pipe and shorty. it increases the power of the bike (2002 yz85). it flies! definiately worth the money, if you are looking for an increase on your 2-stroke.

A: Yes, you shouldn't have any fitment issues with your FMF Shorty pipe. I would install the FMF SST Pipe and see how your bike runs then go from there. Jetting may be necessary. If it is, I would recommend getting the JD Jetting Kit which you can find here:

A: The FMF "SST" pipe would need to be run with the "SST" silencer.

You could run the FMF "Fatty" Pipe on your blaster with the Stock silencer or the FMF "PowerCore" Silencer.
Q: Will you have to re tune the carb?
