Outstanding quality

I Installed the setup on MY2013 WRX with around 6k on the car. Installation was a breeze, even using jack stands and simple hand tools. Overall fitment is perfect and gives a deep rich boxer sound with no drone. If you are looking for a noticeable exhaust that isn't incredibly loud, I highly recommend this product.

Good stuff

Solid product looks great and sounds great, noticeably louder than factory exhaust but not to loud to get cited. Installation was a breeze from the cat back but the down pipe not so easy, bolts from turbo outlet are extremely tight I only have 1300 miles and snapped a bolt so have extras just in case or pay someone to do it. Took about 2 hours to get it done with a lift and sounds awesome. Access port also benefits exhaust tone good stuff.

    I'm thinking about buying this kit and an AEM CAI. Any idea what HP/TQ gains i might see on a 2013 WRX? Also curious if I'll see and better MPG with the upgrades?...

    • A: Hello, As far as power goes You will see about Stage 2: +15% HP and +24% TQ. We have seen that it does help improve gas mileage, There is no set number but you should see an increase.

  • AnswerQ: SI-Drive I, S, S# still have an effect?  0iyPE5Ia 4 years ago

    After installing this power pack and related ECU map, do you still have the option of on-the-fly switching between 3 different performance modes via the SI-Drive toggle? (I'm hoping there's a relatively tame setting for bumper to bumper traffic situations like the OEM I mode provides)

    • A: The SI Drive is still functional with the AccessPort maps.

    Is the accessport compatible with Canadian 2012 WRX model's?

    • A: The Cobb Accessport we offer is compatible only with USDM vehicles. I suggest contacting your dealership to determine the version of vehicle you specifically have. Thank you!
