no check engine light from the Y-pipe. if you mess with the pre-cats I've heard you'll get a check engine light. As far as exhaust systems go, I like the Artisan exhaust and the Borla exhaust. Artisan exhaust has a magnaflow magnapack (what i have on mine) and 2.5" cat-back piping.... The Borla also sounds good. I'm just not a fan of the Greddy look. but everyone has their own taste and I can respect that.
