This was very easy to install sounds really good can't wait to get the rest of the exhaust
Makes more power across a broad RPM range. Sounds great. I have only ridden with pipe 2x s so its to early to tell on durabuility,but I'm sure it will be as good or better then the other fmf pipes I have had. BEST OF ALL ITS MADE IN THE U.S.A.
The install was easy and as ausual the FMF performance is great .
Put on my sons kx250f. Sound is down right evel. Power is comparable to his older exhaust (aftermarket). For the price, it's a good muffler.
Would definitely recommend this to anyone wanting to
Enhance your performance or looking for a
Pipe that looks good. FMF!!!!
Love the silencer and it's a little smaller than stock.. has a nice sound..
The coupler pipe In-between the header and the muffler was really tight and I had to use a mallet to hammer it on but otherwise I like the system a lot.
This is the sexiest exhaust east of the Mississippi! Best Quality and performance too!
Put this on my 16 kx450f and it woke it up a lot! Worth the money in my opinion and it looks great
Did a lot of mods to get bike running the way I wanted--needed a lot more bottom end power than stock setup. This was by far the best change I made. More power across rev range, but also smooth delivery so power is really usable. I would put this pipe on any bike for sure.
A good gain in low end and this baby barks like a dog!!!!!
I had the bike apart for suspension work and researched the mufflers to bring the stock kawi screech inline with ama requirements. I also wanted a spark arrestor for free riding offroad. This is the only one i could find to meet those needs. I am pleased.
I could really tell a difference from the bottom end up till about mid range with just the slip on. It sounds great and looks great. Highly recommended.
You can feel the weight difference in your hands from stock to this beauty. Power is noticeable instantly. This will probably be the only engine mod I do to my KTM.
Motosport was out of the header and pipe together--on backorder for 4 months! so I had to purchase separate at $50 more. Bummed about that!
Lots more bottom end power with this unit compared to
stock one. Pretty loud without insert installed.
this pipe is awesome. I have had it for 6 months now and it looks and performs awesome. it bolted right on to my bike, I also only got the slip on and had no problems with It and the stock header.
Sounds good, looks good. Removable spark arrestor. Con: sticker peeling from factory
This exhaust is a few pounds lighter than the stock silencer on my 2015 KTM 500 EXC. it also gave the bike the sound I was looking for. The best part is that it freed up more power in the low to mid range. As the stock silencer was super restricting
Incredible performance boost.
This slip on made more difference in performance to my KTM 500 EXC than any other aftermarket pipe has ever made to any other bike I have ever upgraded.
Looses nothing on top, but sharpens up the bottom and midrange hit.
Super responsive and fun.
Much lighter than the stock piece as well.
It's loud when it's hitting, but you can control the noise with good gear selection and rpm when you need it to be quieter.
It works, it's light, it bolts right on, and it looks cool.
Nothing not to like !
There are a few instances where the FMF muffler will only fit an FMF header, but that's because FMF was not able to get the gains/fit they wanted with out making it an FMF only version. For the most part these are KTMs only.
