Hello: Just turned 50 and decided to swap out my 2015 WRX sti Sport for the Fiesta ST. Picked it up on Friday. Drove both the Focus ST and the Fiesta ST and preferred the Fiesta. It reminded my of my first new car, a Firefly (size wise). I'm just tickled with this car. Had to go back to the dealership on Saturday to retrieve my garage door opener and a young guy pulling in just in front of me also drove a Shadow Black ST. He'd done considerable mods to his unit and we got to talking. Certainly got my ideas going. I think he was a little surprised I was as interested and could speak half-ass intelligently about some of the upgrades I'm interested in (given I'm female). So...what are the recommendations for the following?: HID light kit, tasteful exhaust (after all I am 50 ), stage 1 upgrade and intake. Thanks for any suggestions and any flags as to what aftermarket products/suppliers one should steer clear of.
