I remember somebody mentioning this a while back about the DC Sport Cat-Back Exhaust, and how it was some type of scam. I was checking out this website, yoparts.com, and it actually seems legit. They sell a lot of parts for the V, not including universal parts.
If anyone wants to check it out, click on the link below and select the 2007 Nissan Versa S 4 Cyl 1.8L. It's priced at around $800, fair deal?
