I bought the sport cat back exit in stock location with twin 4" tips. Install was a breeze in my driveway with a couple of jack stands, less than 2hrs. Quality parts and install instructions. Looks great, sounds sweet, nice rumble outside, quiet inside. Last day trip I averaged 17.1mpg for the day (190 miles) on a variety of back roads and city and some highway.
