I am taking delivery of my new to me 05 cts-v on wednesday and I am wondering what kind of parts to put on the car to get started. It already has a borla exhaust system on it. From what I've read the next step would be cold air. I'm not trying to spend a bunch of money but maybe 500-1000 to get the most gain for my money. I also may consider the washers in the rearend like what was on another thread to help with wheelhop. I'm not really great with working on cars, but I have enough common sense and can read instuctions to be confident with a little help by my cousin that is a cadillac mechanic although he's not real familiar with the v's. Any help would be greatly appreciated..
