Kooks 1 3/4 header and exhaust question

[redcollection8]

Hey so I did some searching but didn't come up with a definite answer so with that being said I am looking to get the kooks 1 3/4 headers with 3" collector to 3 inch O/R X. Now my question is is it worth getting the 3" catback with my power level or can I just stick with my 2.5" stingers? If it's better that I go full 3" are there any other options besides mac or the $800 bassani/magnaflows
