What size spark arrestors for Shearer Pipes

[platinumjason]

I decided I want shearer pipes. Just wondering what size OD spark arrestors I will need for them and where is the cheapest place to find them. Thanks for any replies. Also I heard you either have to remove the stock airbox or notch out the sides for shearer pipes to fit, this true? thanks

Best to remove the airbox.

use the sparkys I bought for the t-5s I used to have a couple of years ago, fit perfect on my shearers. ditch the air box, the stingers are tight with pod filters as it is. could not imagine trying to fit them around an air box.
