Start with a tune.

After the tune, which components will give more bang for my $$? I would guess the exhaust system, but I have no idea.

Yeah usually exhaust and intake, otherwise bigger turbo. Kinda depends on the car though. Keep in mind with all of these things you get what you pay for. If you want a good hi-flow cat you're gonna pay good money for it.

Exhaust first. Get a new downpipe, and high flow cat, or cat delete, then any cat back system. And get a boost controller + good tune, that should give you a serious boost in power.

Next would be intercooler upgrade and intake.

I found a boost controller, the GReddy ProFec-B


For the exhaust, I'm thinking either the:
Invidia N1 Catback Exhaust
or the Borla Catback Aggressive.
Any foresight there? The pure yet loud sound is what I'm going for, not the tin can rice cakes =P

Also, are these two systems the same thing as a high flow cat, a catback system, and a downpipe? Or are each of these separate components of the car?

They are all separate components. This diagram shows the differences pretty clearly: http://www.allfordmustangs.com/forum...st-diagram.gif

A high flow cat replaces any of the catalytic converters on your car.

A downpipe can be with or without a catalytic converter ("catless") which you may or may not be able to get away with depending on your state's emission laws or if you're willing to circumvent them.

A catback is exactly that: an exhaust system only from the rear catalytic converter ("cat") to the back of the car ("back").

Emissions problems are likely going to be something you will need sort out. That includes state regulations for emissions. This is not just testing the exhaust emissions of the car, but often fiddling with the exhaust of a car can cause issues for your car itself, usually manifesting itself in the form of a check engine light. I don't know of any states that pass your car with a CEL. There are ways around this and to fix it but can often be a pain -- point being, either find a custom setup that someone's used and had success with before or buy a complete exhaust system.

Often times, people see good power gains from doing an entire turbo-back system along with a tune. The additional benefit of a tune is that you can usually get rid of any pesky CELs that are being caused by the new exhaust.

Getting emissions sorted out isn't the only problem as many states have noise regulations as well. Additionally, some states like Missouri where I used to live have made it illegal to swap out individual components of an exhaust system. If you want to modify your exhaust, it must be sold as a complete ("full") exhaust system.

To get around this you can either do the work yourself or find a shop that is willing to do the work anyway. I just had to call around to a number of shops until I found one that would modify individual components.

I would recommend asking around on a Mini specific forum where many people will have gone through every stage of the tuning process including dealing with all the issues I've already stated.

Good luck, I hope this helps.

Enderx hit the nail on the head!

As for which cat back, i think your going to have to do a bunch of listening of audio clips/videos to try and determine which sounds best to you. They will for the most part all provide the same performance from a free flowing design, you just have to pick what sound you want, and how much you want to pay for quality of build and materials. High end exhaust components dont typically yield more power, they are just top quality materials and impeccable build quality that will last a lift time.
