hello! im new to this place, so hi to everyone!

abt 4 months ago i bought a 99 triple black mustang cobra. it was a one owner car it has 66 thousand miles and i have documents of every service ever done to the car. everything was done at a ford car dealership, but i have a couple of conserns...the first one is that the car is from california. so they have a different type of exhaust,(thats what ive heard) i live in wichita kansas, do you guys know if that takes hp from the engine?. and my second consern is that i just read abt 99 mustang cobras having some type of recall fix problem, do you guys know anything abt that? and what should i do? i think is something abt not having the horsepower that is supposed to have...plz help me out!
