best headers for money

[mattrobs]

i have recently bought a 370z base model 2009, and was wondering which headers i should get. i'm looking to to spend around 700.im pretty set on get getting long tubes as well as some hfc's.does anyone disagree on long tubes is thier decent clearance for speedbumbs rough roads etc??

ive looked into some ppe headers & z1 motorsports headers but there all quite expensive.im open to any suggestions on the type & esp the brands of headers also if i even need hfc's or test pipes with the long tube type setup.if i do what are pros n cons
