Who runs FMF spark arrestors?

[Mile9c1]

Looking for feedback here. My bike is stock - are FMF fatties and turbine core spark arrestors worth the $500 it's going to cost to get them? I don't plan any more mods at the moment.

 

I need the spark arrestors for orv trails and Silver Lake. I like T5's but sparky's or the hush kit look annoying.

FMF probably has one of the best spark arrestors avalable. Every one elses look like a last second slap on mod. FMF's doesnt really use a screen. It has a core that spins the exhaust like a tornado. It forces particles to smash against the out side wall. A spark arrestor has to ethire trap particles to a certian size or break them up. FMF's break them up so there is no screen to plug up. Or this is what I have been told.

I got away with out sparkies for about 4 years at silver lake and then one DNR guy would not let me in because there was no forest approved stamp on the silencer. I used to run wire through the stinger when they would check with a stick but this guy looked in my pipe with a flash light and that was that. Bought the turbines at D.A.R. racing next door and have never had a problem since. Mine stuck past the grab bar a 1/2 inch and would hit if you were doing wheelies and tailed it so I got a six pack rack. I couldn't tell any power difference and like the six pack rack (PRM brand)

I have fatty's and bought turbine core 2's this weekend. i couldn't tell a difference in power from the powercore's that were on it so i say there good but i'm no expert. there legal tho. keeps even the biggest P.I.T.A. rangers off your back
