Pulling Opencart header to wordpress – SEO

I am trying to get opencart header to wordpress. Opencart is installed within wordpress directory within “store” folder. With some help, I am able to get opencart page into wordpress. The below code is saved as headerX.php and it is called in page.php withing wordpress. This pulls the entire page into wordpress home page. Everything is good uptil now except that $response->output(); will get the entire opencart page including the products into the main page.

How do I get only the header and footer into wordpress and ignore (or not include) stuff between?

Thanks for any help.
