I'm all for performance modifications just be aware going to long tube headers can potentially void vast portions of your warranty (if any) and if you're subject to any state emissions testing or inspection you could have a problem. Any time you remove, relocate or alter the OEM cats its a violation.
You don't give your location. If you are in Florida, you are OK, in NC or VA or CA - not so much....
If you're not doing heads and a cam, don't waste your money on headers....
If you want a nice (better or louder) sound, then invest that header money, into a good after market exhaust.... Lot of good choices out there from Corsa to Billy Boat to Magnaflows to Borla Stingers... Take your pick.
Good luck....

Long tube headers, I have the LGM pros, CAI and tune is 40 HP or 380rwhp on a LS2.
