The best system is the one YOU like best. They all put out nearly identical numbers when jetted properly. Find one that cosmetically appeals to you and one you like the sound of. Its the combination of mods that make for the quicker bike, not just a single item.

The CT system is good...but if the numbers you throw out are just from the Dirtwheels shootout then they are a tad bit flawed. The yosh system wasnt properly jetted and they reference that in the shootout. Around here every ATV shop i have spoken too said that with a little air and properly jetted you will make the most gains with the Yoshi pipes...not one or two now, I am talking every single one I have spoke with ... 4-6 different shops. They say the power gains, especially mid-range, is sweet...good pull all the way through...

With that said i dont thing you could go wrong with CT, Pro Circuit, Yosh or Muzzies...how you ride and where you want the biggest pull should dictate which of these you chose...

Every quad was jetted correctly (I know the guys who did the shoot out ) altho they were all jetted per the pipe specs which every quad is different and will not except all req. jetting ... At the shootout they did 15 pipes in 2 days , that is a lot of work and there is no telling
which pipes were rushed . Also the tires provided by Dirtwheels for the shoot out were 8 in Hoosers which makes a big diff on the dyno
With my set up I only turned 29.9 HP on Maxxis Razrs 2's with the Hoosers I hit 35.6HP , how it works out like that I have no clue but
with the power I have to the dirt is a night and day diff from the other pipes that I have tested . With the CT race tip it should increase
more HP considering the tested CT with 7 discs is very choked off. I would like to of had the oppertunity to try out the Yoshi cause one
off the Rappy's I ride with has one and there is a big diff with the Yoshi compared to a BigGun piped Rappy..

Anyway IMO you can only ask so many people about pipes but when it comes down to it your the one who is going to ride it and no
matter which pipe is installed there will be a big diff compared to stock set up.

I have a Bills Full exhaust system. I got the full exhaust for around $400 and it work awesome. I have tons of bottom end power. it's a little load but not like the alba pipe.
