Hello everyone, I just purchased a 2015 V6 Fastback. I have never owned a sports car or muscle car prior to this, and I am excited! It's my daily driver, so that's why i decided on the V6 instead of the GT. I was pleasantly surprised when i popped the hood and it already had a CAI and throttle body already installed. It also has aftermarket exhaust, although I am not sure if it is cat back or axle back. The exhaust is by Flowmaster. I look forward to learning all about Mustangs!
