full header back exhaust systems??

[joka1]

before anybody says it... i did use the search and didnt find what i wanted!!
now with that out of the way i am looking for a header back 2 1/2-3 in exhaust with a high flow cat and was wondering if anybody manufactures them or do i have to buy the cat and muffler and take it to a muffler shop and customize one.....?????

The closest thing I know of is the Cork Sport 'Power Series'. There's a diagram of where it bolts to on the site.

Take a look there.
