I bought mkII BF xr6 at christmas and have finally decided to start doing some modifications. I've been browsing these forums for about 4 months getting ideas on what mods but I'm stuck on what to do first. I've been looking at CAIs, underdrives, and exhaust setups so I'll probably end up going with one of those. I have some cash I need to get rid of, but the problem is I'm really picky. So any advice on what mods to go with first would be appreciated. Thanks, Brendan.
