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.

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

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.

This FMF system is the PERFECT fit for DRZ400SM! Installed in 20 minutes-flawless fit.

The product sounds amazing on my 2016 yamaha wr250f. The tip was cracked when it was shipped and the factory exhaust clamp does not fit! Also you are going to need to buy a tuner if your bike is fuel injected because it barely runs unless you are almost wide open throttle.

Put on the fmf gnarly and fmf shorty silencer and woke up the bottom end. made woods riding a lot more manageable. fit was excellent,finish could of been better but chrome polish cleaned it up.
