im new to this whole car thing and i was woundering what you would reccomend for an exhaust for a 2000 stratus 2.4L and to verify what kind of car I can provide pictures

 

I'm new to car stuff and I have a 2000 dodge stratus 2.4L and I was hoping you could recommend an affordable exhaust set for my car. I would like it to sound louder. It has an auto stick feature(slap stick) so i can get high rpm's with little effort.

 

So I have a 2003 Dodge Stratus sxt 2.4 L coupe. I just got a cai from someone who gave it to me along with a flowmaster exhaust, don't know the guy, my dad bought some Challenger parts from a guy and me and his roommate started talking and he gave me that stuff. Ok so my problem is, is that the stock intake on the car has a small computer system that has a dirt sensor on it, I'm not very "fluent" I guess you could say mechanically, I'm new to this. Is there some sort of adapter I need to hook up my intake as I believe it won't run without it? I just need help in this situation, any help is appreciated.
