I was wrong MAC does not have for your year car yet. As far as a Chip Unless you need it do not get it. I have heard from a million people that it did more harm than help. If you need it to fix something than get it, like if you have a new cam or blower. If you are heavly modified get it.
A h-pipe can have cats on it. If you get an off-road than it does not have Cats on it. You get better sound and more horsepower with out Cats. With the h-pipe from MAC you can use any aftermarket exhaust system with it.
If you have anymore questions please ask.
