I dont really know to much, but i was hoping someone sould help lol i have a 2007 civic and i wanna get an exhaust system but idk what to look for, if you guys could help a brother out it be much appreciated.

Yoshimura!!! A Flowmasters would sound good if they make a full systems for civics.

If you don't have an Si....then Skunk2, Magnaflow and Tanabe make full cat back systems for the car.

Might be hard to get the tanabe, and it is a bit pricier, but that is all that is really out there in terms of perforamnce exhaust kits for these cars.
