I'm still stationed in Seoul, South Korea. I come home in about 40 days. I've been stackin up money to do a few things to my 09 SS/TC. I was thinking about doing the exhaust. I was thinking about the Hahn MaxFlow CatCon 3" down pipe and the 3" CatBack exhaust. My only question is will I have any fuel management problems when I do this. Will I have to change anything with my car? I don't know much about these things. Please help

if your just putting exhaust on your car you wont need to do anything with the fuel.
