The pipe looks great. Installation took about 5 minutes. FMF indicates that mapping isn't necessary in most cases, but I did it just to be sure. The sound is great, power was increased through the mid range. Great product.

The least offensive spark arrestor
Let me start by saying my local forest service ranger told me that he has never heard of any fires being started by Sparks flying out of a motorcycle exhaust . I am one if the better motorcycle mechanics around and from my experience , Sparks are never flying out of an exhaust . My cr450f would throw a 2 foot flame out the back when the intake valves were tight , but not sparks . So to be legal we all get to buy something we don't need . The pro Moto spark arrestor is less money but adds a significant amount of weight , far from the center of gravity , which can make it feel like twice as much weight. I didn't want to add pounds to my new bike so this seemed like the better option . It is 1 and a half pound lighter than stock on my kx250f exhaust

THIS IS A WIN
I didn't order the carbon fiber end cap model because I ride a lot at the sand dunes and I didn't want to sandblast the carbon fiber over time I wanted this pipe to last. I also ordered the FMF titanium megabomb header to complete the exhaust on my 2017 kx450f. I also called FMF customer service and make sure I want it need a tune after I did this upgrade to save time and money. The bike with the FMF system looks good sounds good and performs great. THIS IS A WIN!

Nice muffler
Very happy with this purchase. Put it on my 500exc. This muffler is definitely a few lbs lighter than stock. The stock 500 exc muffler is also very restrictive. I put this on and had the dealer remap the bike and it runs great. Feels like it definitely gained something on the top end with no noticeable loss down low. The sound is exactly what I was looking for. Louder but not obnoxious or over the top at all. I was also happy it comes with a spark arrestor.

Overall very nice fit , quality piece very well made and improves the sound without being too loud. Instructions should mention that you don't use the stock spring.the unit didn't have a hook for the spring but I question whether I had the right part but a call to FMF tech help told me yes they make it that way.

Best thing Ive done for my 500exc yet
This pipe is absolutely phenomenal. Does everything it says it will do and is very versatile. The removable spark arrestor is awesome for when I wanna open it up in the desert. Better yet is the fact that i can throw the arrestor in during the summer for some woods riding and dont feel like im sacrificing the whole reason i bought a pipe. This pipe and a slight tune has done more for my bike than i anticipated. The pipe ialso looks great in comparison to the factory pipe. No wierd markings or heat checking after it gets hot.
Still looks great after tons of trips to the mountains

Awesome Muffler
Bought this item in an attempt to quiet down my bike it's a little loud with the stock muffler. I decided on the FMF because my son has one on his bike. I was not disappointed the craftsmen ship it's great and it fit without any mods to mounts or header pipe. As for the sound it is a little quieter than stock, next I will try the quieter insert and see how that works?

Good performance, lighter than stock
Replace stock muffler with FMF and it is indeed 1 1/2 pounds lighter. This was my primary reason for changing.
