hdegenaro on "[Plugin: WordPress SEO by Yoast] Attribute of Title"

Hello,

I like to know, how do I prevent the title example:
"Product | Site | Page 2" does not contain the attribute "page 2". This attribute appears, due to the limitation of products per page. Could someone tell me, what part of plugin, I could remove this attribute?

Thank you.
