There are many ways to check for CEL codes, including the Dealer option mentioned above.
There are hand-held devices available at auto parts stores, there are engine tuning devices like the popular COBB AP, and there are big $ diagnostic devices at auto shops.
It might give you some peace of mind if you find out what the code was, if you also get some indication of whether it may reoccur again at the same time.
I'd find a competent mechanic familiar with Subaru performance cars and get them to check it out. You might need maintenance services later, so it'll be of future benefit too.
