Im looking at either the banks catback, or the apr carbon intake. Which will give me more noticeable gains?? Or should I put the kabash on both of those and get the bullydog rapid power module???

Toe, I saw on another site you have the banks. Do you not like the sound?? Would I be better just hacking the muffler and straight piping it? The reason Im considering the Bully Dog kit is its plug and play, can pull off for warranty work and throw it right back on. (until i can get a tune, 36,000 here i come =X )

You don't say what engine, but from comments it sounds like you have a tdi?
No exhaust will do anything for a tdi until the dpf is removed. You will get no sound change and no power chamge. You'll save weight and have better looking tips.
An intake will be useless for the majority of drivers as well. Even with tracking my car I'm seriously unsure whether I'll need an intake.
Your best bet for power is getting software. If you can remove the dpf then do that.. there's virtually no negative to doing so (imo) and then you do gain something from having an exhaust.. and even then you may not get anything from an intake
that's an add-on right? ie. it plugs into the car. If so... our ECU's are learning, and they will eventually adapt. You have to actually update the software to make the car faster. Go with Revo, Malone, or Unitronic.. you won't regret it.
An exhaust and intake may not give you large hp/tq increases, but you will make it easier for air to flow through the engine (after all, an engine is technically an air pump). This will allow the engine to run more freely, and also improve throttle response. You'll notice when you hit the throttle, the car engine responds quicker.
Also, in regards to the problems ToeBall had with the Banks exhaust, they've made changes to the system to resolve the issues with the rattling. Toeball, have you contacted Banks Tech Support to see about getting it replaced with the newer setup?
And me personally, I would do airflow modifications to the engine before a power adding module. Your engine will thank you for it in the long run.

That DPF is definitely ridiculous!
With that said, I still recommend an intake. Regardless of the exhaust restrictions, an intake will still reduce pumping loss during the intake stroke while expending less energy to do so.

The best thing you can do for power gains, besides removing the DPF, is to flash the ECU with upgraded software. That's it. The rest of the car's easy gains can be found in handling, braking, grip, and the driver.. and trust me when I say that the car has plenty to gain and plenty to show for itself once you get there.

On a N/A car I say it free up the stroke of the piston but on a turbo'd I dont see that.
Although you could look at the intake as performance gain in respect to cleaner exhaust and this leads to less gunk circulating back through your EGR system and cleaner intake manifold
Anyway you look at it though the more free the engine breathes the more efficient it will be.
