    Downpipe and Tune...is that all?

    Hello everyone!

    First and foremost, I drive a 2012 WRB WRX with just a Kartboy SS and front/rear bushings installed, all else is stock.

    As the title of the thread suggests, I'm in the market for a downpipe. I'm aware that the replacement of my stock downpipe with an aftermarket one will require a tune. I plan to go OS with a Torqued Performance Stage 2 setup.

    However, I'm wondering if there are any other parts I'd need or want for the installation of the aftermarket downpipe. I plan to go with a Divorced Invidia Catted downpipe. Any information/input would be greatly appreciated.

    Thanks in advance!

    Steve

    I meant something like an adapter for the downpipe to the stock catback, or turbo to downpipe gasket.

    Along the lines of:

    GrimmSpeed 3in Downpipe to Stock Cat-Back Adapter Subaru Turbo Models 077044 at RallySportDirect.com

    Permaseal MLS-R Turbo to Downpipe Gasket Subaru Turbo Models TUR010 at RallySportDirect.com

    Just wondering if they were necessary in order to achieve proper installation.

    First time I hear of Torque Performance unfortunately... after checking out their site, I doesn't seem like you'll anything else other than the downpipe to go to Stage 2. Same as Cobb.

    Yes, you'll need the grimmspeed adapter to properly attach the 3" downpipe to the stock catback. Should also get a new donut gasket.

    I like the Cobb for the reason that its a direct bolt-on to stock exhaust. Only thing you need with theirs is the heat shield so you don't have to cut away at stock one.

    You'll also want some PB blaster to spray on the bolts to help get them loose. If you are ever thinking about being able to accurately monitor air/fuel ratio, a wideband o2 sensor is a great investment, and when changing out the downpipe, this is a great time to install that...Just a thought

    If you don't have a boost gauge, the AP can be used to monitor your boost (and all other data obviously), so it is helpful to have a method of mounting it. Otherwise, a boost gauge is a good investment as well.

    - breaker bar
    - good clean 6 point socket for the DP bolts on the turbo
    - adapter to attach the 3" DP to the 2.5" OEM catback
    - possibly new bolts to connect DP to CB (your DP may come with some)
    - new heat shield or cut yours (diy's are out there for this)
    - very cold beer, very!

    I agree with the heatshield comment. You will need a new aftermarket one or cut the stock shield.

    Does it pay to purchase a new heat shield, or will cutting the stock heat shield suffice?

    When wrenching I usually go with a ****ty light American beer.. although that's mostly because I live in TX and it's hot as bawlz here.

    The stock heat shield is fine, and trimming it is easy.

    But if you ever need to go back to stock, you don't need able to use it again.
