Paired up with a Borla catback system my 2.5rs sounds incredible.. The shop had a slight issue with fitment though. They were able to bend the headers down a bit to line up with the downpipe. The hanger for the down pipe had to be relocated. 4 stars just because of the fabrication that needed to be done. Otherwise, it is perfect. Maybe add info on the CEL fix, like what O2 sensor it is supposed to go on. They left it out, but so far no check engine light.
