What order to purchase mods?

Hey, I have a question that I have been thinking about for a while. I couldn't find my answer in the forums. As soon as I sell my current car, I am going to start looking for a nice 2006 STI, and was wondering if it was a bad idea to get a full exhaust before I get a tune. Will a catless TBE+UP cause the car to run lean with the stock ecu? I wonder this, because I want my first mod to be exhaust because I love the sound of the boxer engine, and I didn't really want to drop $1500 all at once for a AP (if I decide to go with that) and exhaust.

If you can't do it all at once, I recommend the following:

1. AccessPORT.
2. Downpipe.
3. Cat back.

I can do it all at once, I'm just wondering if it will cause the car to run lean with full exh. What about with just a catback?

The reason is I want to get a mod every once and a while instead of drop all my money at once, and at the beginning, the stock performance will be enough for me and I want to get a AP once the stock power becomes a little more boring.

with just catback its fine, but if you have DP then you will need a tune. so you can get catback right now with out the tune.

then when you are ready for the DP, get it and get it tune. which means buy the cobb AP

Its not going to hurt the car to get those items in any order. Just a catback alone will do very little. From a performance stand point, Paul has the right order
