I have these on my Ranchers, Recon, and 250EX. We have a new 96dB sound limit here in Calif., so I might have to run a quietcore??? I agree with the "less sound means more ground" philosophy, so I am happy to quiet my bikes down. And, I ride the utes mostly in the national forest anyway.

So, how many disks are you running, and how loud is it??? FMF says run 11-13 disks for all-around power, and more for increased top end (but this would be wickedly loud!). And, a quietcore and/or less discs for more low end (but never less than 8 discs.).

I need relatively quiet bikes, so I guess I will have to tune for low end (which I kind of prefer anyway). I am currently running 8 disks, and no quietcore, and although I have not tested the sound, I think it is borderline 96dB, if not over. I was thinking maybe the quietcore and 8-11 discs, whatever will keep me below 96dB???

I run the MegaMax2 on my 01 Warrior. I like it. Not too loud and has a good power curve. As far as the adjustments I dunno, I've never really messed with mine too much.

 

So how many discs are you running? It comes with 11, are you just running them all?

 

I just counted and it looks like all 11 are in there.

How does that work? More discs equals more top end power and less is more torque? Or is it the other way around?
