    Cobb down pipe

    Purchased Cobb down pipe, one suggested by rally sport direct, same time I purchased Invidia N1 catback exhaust. Exhaust has been installed
    Haven't done any other mods yet, but will be putting top mount inter cooler and cold air intake soon.
    Question is.....any disadvantage to installing down pipe on car now? Any advantage?

    Thank you in advance

    Not sure the advantages or disadvantages but make sure you tune it before you install the dp if you haven't already.

    I'd go with an Cobb ap v3 easy functionality and very user friendly. I'm not to sure about the pro tune though.

    There is a disadvantage to installing the DP now. That is that it would be very bad for your car, as you have no way of tuning for it. Your car needs a tuning solution, whether that be a cobb access port, or a tactrix cable. You will need one or the other regardless of if you use off the shelf tunes, or get a pro-tune/e-tune. The tactrix is cheaper, and you can do open source tuning using the cable (you need a laptop too). The AP is a handheld easily used device, that is convenient, and doubles as a gauge. I would suggest researching both and deciding what route you want to go. To be honest, a pro tune at this point is not really worth the money unless you want to stop at stage 2, which in that case, the pro-tune is the way to go. A pro-tune is always better than an off the shelf map as it is designed specifically for your car. But if you are planning on further mods, which is sounds like you are, then I would recommend waiting until you get at a point where you "outgrow" the off the shelf maps, and at that point get the pro-tune.

    Regardless of which tuning route you go (I mean cobb AP or tactrix/opensource), you should perform data-logging to ensure your tune or "Map" is functioning the way it should. There are people here that can help you look at that.

    Downpipe and tune need to be at the same time. Also get a cobb or aem intake if your going the AP route because those are the only intake's that work with the AP maps.

    I personally use a Cobb AP. I have the ots maps and 2 custom protune maps. It is great to be able to datalog tune and act as a gauge. It's also small and ultra portable vs laptop. I do a good amount of data logging and monitoring to make sure my car is happy. I've had 2 WRXs and 2 Cobb tuners, I've had great experiences with them and I'll continue to use them. Just my 2cents.

    Thanks all. Sounds like I might want to do Accessport and after done all mods maybe pro tune. Appreciate all input
