I installed a new catback borla system last week (140914). The thing sounds great. I love it, but ever since I fired it up I noticed the mpg dropped significantly. Before the exhaust, the computer showed about 13 mpg. Not great, but whatever. Afterwards it is showing 8.7 mpg and the number keeps dropping the more I drive.
When I slightly press the pedal and get the rpm to 1400, the readout shows 2 mpg. I don't remember it ever showing it that low before. I don't drive this thing hard at all. It has 1600 miles and I'm babying it.
Anyone seen this? Any ideas?
