    2011 WRX limited with Cobb stage1 and a catt less down pipe on the way, questions.

    I ordered a married cat-less invidia downpipe with adapter to hook to stock exhaust back how much more hp will this make? Next mod will be intake and lay off for awhile. Thanks Chris

    You need to run stage 2 with a modified DP.

    Is the Invidia catless pipe one of the ones Cobb has an OTS map for on their site? Or are you getting it protuned? The Cobb site will tell you how much power to expect.

    If you're going to run an OTS map with your intake, then you also need to buy one of the intakes they have a map for. Otherwise you'll need a protune.
