if you have stock exhaust it wont do much if you have aftermarket it will be loud as hell so i would say high flow cat.

I don't think you should get a test pipe unless you are making a lot of power, otherwise, you won't see a big difference only that it is louder.

I have a test pipe on mine and it makes the car stink from the fumes and puff black smoke. I would get a hi flow cat if i were you.
