Make all the forums look like the index page

Hi there. I have saved the theme Im using as bbpress.php, works great on the index page:

http://makermentors.org/forums/ (this is setup within a page of wp, using an inner container on a content band)

But when you click on a forum, it goes full width like this:

http://makermentors.org/forums/forum/maker-mentors-2/

How do I make the entire forum follow the same style as the index?
