Default header suggestions?

I'm thinking about putting headers on my car. Right now it's got a basically stock 2003 LS-6 (405 hp) w/ the stock f-body manifolds and cats. The only change to the exhaust is the after cat Y and the cat-back. I think I know what the response will be, but I don't know if I want to go with LT's or the significantly cheaper MAC mid-lengths. Any suggestions would be appreciated!

i have MACs and i love them; if youre going to lower your car then id look into the MACs, just dont get their cats (they flow worse than the stock ones). The midlengths also help you keep some lowend torque
