What does a strut bar actually do for the car?

I really dont know much about cars but i want to hook up my lancer. Recently I bought a strut bar and am waiting for it to come.

Many people have told me different things about what a strut bar does but most of them were still not sure.

Also, i am looking for a good exhust to put on my car but dont know of any. help

 

Maybe not the best explanation, but at least a simple one:

Hold your hands out in front of you, and form an L with your left thumb and index finger. Now form an inverted _l with your right thumb and index finger. Should look something like this l__l Imagine that is your front suspension, it is somewhat secured at the base, but the strut towers don't have a lot of support. Imagine adding a bar across the tip of your index fingers, so you've basically now created a box. The strut bar should lessen the "flex" of the front chassis during aggressive driving.

 

very good explanation, actually. Also keep in mind that strut bars with 2 or more studs on each side keep the struts from rotating. But like Hammerli said, the main purpose is to keep the topw of the struts from moving, inward towards each other or away from each other, thus holding the car more rigid while under a load (aka cornering).
