This only fits the Fatty, not the SST

I gave this a 3 for fit because I have to cut and weld it to fit since there is no FMF pipe that fits the SST, apparently the SST and Non Silenced are shipped together. There is no mention or selection for it to go with SST or FATTY expansion pipe, the SST is 4" too long, in most cases that's a good thing, just not in this case.

T-4 complete pipe on my 2000 honda xr650r

Aluminum chassis and freshly redesigned water pumper engine coupled to the T-4 and you've got endless power from idle to peak rpm. Just a monster to start with but pro circuit makes it a rabid beast. So happy with my bike and the T-4. A choice well made that keeps delivering every time I twist the throttle.

moose racing straight section heat shield

Great product with very versatile mounting brackets. I mounted it over the existing heat shield on my 2012 YFX 450R and it worked great. The price is high, but it was worth not burning my leg.

Great Fix

I loved and love all of my FMF Shorty pipes for 2-strokes But liberal California requires spark arrestors to ride legally My RM 125 1995 Has no current applications, being so old, but this fit the bill. I'm just a bit disappointed in FMF they couldn't say one way or another if this would fit. Shame. All I did to retrofit, was cut offf original Shorty pipe amd install new silencer/spark arrestor. Voila, Cali legal

Power core 4

Bolted on to my 2015 WR450F in less than 5 minutes. Great power improvement along with GTYR competition ECU. Woke the WR right up. Sounds good with out being overly loud.

You get what you pay for

I purchased the carbon full exhaust system with header pipe about a year ago for my 09 YZ250F and have not been impressed. The mid mount bracket cracked and broke off during a trail ride this week. The end cap top hole broke out because the spark arrestor insert and reducer cone don't fit well together under the end cap. The pipe is too loud (just as loud or louder than stock). I feel bad riding trail with it, but fine for track. All the can bolts came loose at some point, had to replace and thread-lock them. Header bolts keep coming loose. End cap bolts are soft material and strip easy, had to replace those. Pay a little extra for something with better quality. For strictly track use, the system is ok. Still produces good power.
