I bought this for my KTM 125sx. Great product! Installed in 10 minutes, works great, sounds great, and there's definitely more power than the stock muffler which is smaller and doesn't have a spark arrestor. I would definitely buy this again.

Unless you need a spark arrestor, stock is probably better for a pre 2002 KX250. The pipe is short and barely meets the chamber outlet. My other FMF muffler fits fine in the same position. Seems like shoddy quality control...
It is also VERY loud after about 20 min of riding.
However I needed to be USFS approved for the woods, so too bad for me.
Try a little harder FMF...
First 1 I got was damaged, mike in customer support was awesome I shipped it back, i got the new one 2 days after, it was perfect, looks so much better then the stock pipe, power is better speed is better, thanks guys. 2006 Yamaha Blaster Special Edition.

I was worried about putting a spark arrestor on my 125 because of power loss but was extremely pleased to learn i gained power when combined with the FMF Fatty! Super pleased with the product!! would not hesitate to order again.
easy to install, passed sound test at a local hare scramble race, the power felt great. I would recomend this silencer to any one looking for a durable quiet spark arrester. I removed a titanium silencer with no spark arester and couldnt notice any power loss at all. I crashed down a big hill in rocks and the silencer held up great.
I noticed no difference in power or sound compared to stock silencer. It was a pain trying to get the mounts to line up. On my paticular bike it sticks out pretty far past the number plate. Good silencer if you trail ride and need a spark arrestor, but dont expect any power gain.
i bought this pipe because i wanted to feel the power difference from my 304 procircut shorty and it sounds better and i can get a stronger and longer powerband out of every gear i notice that i was still used to the old pipe and i wasnt gasing it enough so i just slamed the throttle in every gear and the power band kept on climbing not as much low end power tho as the shorty but the snap in powerband really made up for it, great pipe for hill climbin i really have to lean over the bars now. Buy this pipe if you love powerband. Great job FMF!!!
The FMF Turbine Core 2 is going to be the best available option for what you need. It is spark arrested and is quiet enough you will have 0 problems passing sound testing if that is required. Please keep in mind that after installation you may need to re-jet the bike. Make sure to profile your bike properly so receive the exhaust specific to your 2008 KX85.
