if they make it for that car, get an RS-R Exmag. the least ricey 4 banger exhaust ive ever heard. a friend of mine had one on a honda civic.
i did a quick search and it seems that some vendors listed that exhaust for a 2g eclipse but i couldnt tell if it was turbo or not. RS-R didnt show one on their site though so i dunno.
best one ive heard for a NA import
