ripper, I'll look into those, as far as powerwise I'm not interested in to much more than standard, just want a little bit more bite, its my work car so its gonna get a lot of milage, and I want to try and keep away from the petrol station for as long as possible haha! A mate told me to look into a xforce exhaust system, and a growler CAI both seem good on paper, but I need to do more research and need advice on both products, sorry if this has been discussed countless times before! appreciate the help!
