Slick is right here.. we've sold MANY of the new revised Borla UEL headers in our GB and I've seen people with NO issues on a stock tune (no CEL).
But as a safeguard, I'd go with an eBay O2 Sensor Spacer/Eliminator.. few bucks and does the trick. A tune would benefit you both ways.. by removing the CEL and I've seen a STOCK FR-S with a header and tune get about 192rwhp!
Speaking from experience and from a bunch of reviews from people who ordered the Borla header from us, it is truly a great header!
