    2014 WRX Cobb AP Stage 2

    Hi,
    I am new to the forums, I bought a 14 wrx with a SPT cat back just for the sound. Now I want to get the Cobb AP and am wondering if it is smarter to just get a catted downpipe along with the AP and would that be fine for stage 2? Or do I have to get a Cold Air intake to make it to stage 2? Basically I'm looking for the best option for the money because alot of people are saying the stock air box is excellent

    All you need is a downpipe to go stage 2. The AP maps are designed for a catted downpipe. You don't need a intake for the stage 2 tune but if you get one make sure you use the stage 2+cobb or aem intake

    Ok thanks for your help, so is there a map for just catted downpipe with a cat back exhaust? Also would Cold Air Intake AP map be more noticeable power gain than the catted downpipe AP map?

    A catback exhaust doesn't require a tune so it doesn't matter whether you have a catback or not. You can use the stage 2 tune either way. The catback does help the exhaust flow smoother and give you that nice boxer rumble.

    An intake won't provide any noticible power. There will be a slight increase in throttle response and you will hear the suction of the intake and the turbo spool will be noticible.

    Ok cool. There will be more noticeable power from the downpipe AP it sounds like

    So I'm getting close to ordering everything I need for Stage2, after talking with Cobb they said I would need the cobb air intake to go stage 2 and get the full potential but I have been reading some mixed reviews about this. Can anyone drop some knowledge on whether I need a cold air intake for the cobb Ap stage 2? Can I just use the stock one or can I get a cheaper one?

    You do NOT need a intake for stage 2. However if you get one you should get either cobb or aem because those are the intakes that are confirmed to work with the AP maps.
    The stock intake is very good on our cars. Most people get an intake for the sound. It does not provide much for performance except in higher horsepower cars with large turbos.

    If you do get one make sure to run the stage 2+ cobb sf intake map.

    Ok thanks Aaron. i like the sound of starting out without an intake and then add one later when i save up more and load the map for it
