Be carefull with the Banks header. I had one and it cracked a year later. I put a stock replacemant on and it works great. I've heard about them cracking in other forums.
Also the Banks cat-back is way to loud, i just took mine off about 2 months ago and put in a cherrybomb turbo II and can hear the road and radio again.
The performance isnt worth the money, I didnt notice anything worth installing any of this expensive after market crap for performance.
Regear and elec fan conversion!
