I installed Eibach's with 1.5 inch drop along with new factory struts and shocks. The combo handles flat around corners, looks good, and is not too harsh.
Stuts and shocks are easy to replace, get a friend to help with the front springs though.
If you are doing this just for exhaust, why not either cut holes in your bumper cover (carefully) or get a cobra style cover that allows you to run LX tail pipes?
