there is a ton of info already on this forum. Learn to use the search button and you got a lot of reading to do, just don't expect to have it all given to you in one shot. Come out to some of our meets and meet the people, see what people have done to their cars, ask questions and see things firsthand. For instance in the last few weekend meets I have been able to look at people's exhausts, sit in their cars and hear how they sound, which is invaluable to decide which one I want to ultimately get. Sure beats reading about it and even just watching a youtube video. Many of us learn new things about our cars every time we meet up.
