I am trying to figure out how many discs are installed in a stock, out of the box, WB "Pure Polaris" Silencer?

Do they include any spare discs in a plastic bag that are separate from the pipe? If so, how many?

 

I believe my buddy got 8 with hi sbut I do know he got no spares...

 

Mine came with nine installed in the silencer. The instructions say "No jetting" is required from the box, but I want to make sure nine discs installed is "out of the box."

Anyone else?

 

Nine.

 

Thanks Brent!

Did you re-jet your carbs with all nine discs installed?

Did your silencer come with any extra discs?

 

Are you guys sure the ninth one you are counting is a disc. The solid end piece does not count.

 

Rob, they come with 8 disc and a spark arrestor installed. Run 5 disc and the solid back plate. no jetting is required unless you run a hi flo filter or change the airbox.

 

I use my Predators in Mexico at sea level.

The temperatures can get hot and humid, nut never below 60 degrees.

The airbox and jetting is stock.

Considering the above, can I run all eight discs and not damage the engine?

 

Rob, the reason for 5 disc is the stock head pipe is to large, you have to take out some disc to get proper back pressure. sounds weired but it works. I tested this theory at the drag strip, it does make a different.
The thing slowed down when i opened up the exhaust. Gary @ superbike shops discovered this info on the dyno.

 

Will I hurt anything if I leave 9 discs in without re-jetting? I like the loud sound!
