check engine light on after down pipe install

Hey i have a 2011 wrx and just had a invidia catted down pipe installed. since the instillation a check engine light came on i think the mechanic said it was something like turbo wastegate. also the traction control light is on and wont shutoff and the cruise light flashes on and off and doesnt work. any hlep would be greatly appreciated.

Try unhooking battery for a min and then connect it again. My 09 did it once and i did that and it was like a reset i felt like

when the mechanic had it he cleared the code after driving it came back on as well as the other lights as mentioned before, wouldnt disconnetting the battery be just like clearing the code.

Boost spiking MTL. Get the code read. Do you have engine management/tune on there ?

Sounds like no tune, and some one modifying their car and not knowing what they are doing. You really either want to not drive the car (especially in boost), or take of the down pipe, or get the thing tuned. Your car will not run right without doing one of those last options, plain and simple. But getting the code read will also tell you the exact problem. Your car is going into limp mode cause of the new free'r flowing exhaust you just put on and the car isnt liking it much.

Not harsh at all, its probably what I needed. Thanks for the support. I got the sedan in Dark Gray Metallic. Im totally impressed with the car, this is my first subaru, but its definitely a learning experinece when it comes to upgrades. So far I have the Invidia exhaust, and the downpipe as I mentioned, the Cobb Short ram intake, and a short thor shifter.

Plan to order that access port this week.

Thanks again, Ill post with the results!

The Cobb can read and clear. But, its going to fix the issue with a Stage 2 tune also.

If you want a save a bit of money, invest in a Tactrix cable. That cable + a local tuner for the tune will be cheaper in the long run than Cobb AP.

^ a local tuner ? Please explain. Aren't the cables in the upwards of $90-$130. A tuner will charge $250-$350 for a tune.

I've always wondered where this comes out cheaper than an AP. Used AP's can be had for $300-$400

Only reason to get a cable and software would be if you were going to do the tuning/dialing in yourself.

My 2¢

My local tuner charges $150... No need for cable. I have three separate tunes and I've only spent $425 to date on tunes.

If I feel the need I can get a used tactrix for ~$100 but I've never needed one.
