Welcome. Cool car! Mine is a base model. I gotta say glasspacks, the longer the better. Mine are 30". If you can angle tailpipes out and down behind the tires to catch some echo off the curb, you may get a bigger enjoy off that than straight out the back which is more common.
Heres a link to my youtube thing. Three videos there if you wish to hear it. Mufflers are twenty years old and I will spare you from other details. Mild cam and three tube headers are present though so bear that in mind!
