why would you want to remove the endcap and disks? it might rev a bit quicker, but you will loose most of your backpressure and torque. just add a couple extra disks, you can fit several more disks without needing longer screws.

I agree RNGMSTR, why would u want to. That will sound so obnoxious i would imagine. And even in stock form these predators dont have much torque until you wrap it up a bit.

I'm w/ them. I change depending on where I'm riding, but I never got more than all the disk and the spark arrestor. I want to keep public lands public.

thanks so just run 8-12 disc and the noise reducer at the end of the pipe.. I was just trying to jet this. Running 5 univents and k&n with the slip-on. I was thinking of the headers for the slip-on are there any bigger than OEM??

It's not a noise reducer, it's a spark arrestor. I run 11 disks with the arrestor, with no spark arrestor it's slightly louder, but your hurting the performance. more than 11 disks and you loose power, I have tons of dyno time that shows just that. 11 disks for open areas like the dunes, 7 or 8 for tighter trails to get the max benefit.

I agree with every body else the only thing you will do is loose back preasure and make it harder to start when it is cold.

oblkirdo-i run the polaris 38tooth and love it,i also have the w/b slip on and K&N clamp-on, first thing you will notice is the short gears,first -third.also the top end losses about 7-9mph.but what you gain in the bottum is great!!I mostly ride in wooded trails,tight,lots of hills,need the low end grunt.but the then i put on 22x11x10 xct holeshots.more ground clearence and traction,great tires pulls wheeles in 2nd gear easy!the larger size tire gave back most of the top end too. Before the gear change i rode mostly in second after/mostly in third.hope this helps--lance :):) need the the speed,never too fast

Well OBLKBIRDO i'm gonna stray away from what everyone else said on this one. I run my WB pipe with no disk's and just the open cap on the back. It makes it a little louder, but that is how i got the best performance out of it. I was faster than the only predator I raced and he was running the disks in his. It just seems to flow alot better to me. It didn't lose any power like this and in my opinion runs stronger than before.

I've been experimenting also with the W/B pipe and I found out that it runs the strongest with the spark arrester then the 8 disc then the end cap.Ive tried adding more disc,Ive moved the spark arrester,Ive even run it without the s/a in and Ive found that it runs a lot harder with the s/a and 8 discs.
