It depends on what your budget is...
if you can afford a nice pretty TRD
exhaust, go for it!
if you can't, buy a non-turbo apexi n1 universal muffler and go down to your local muffler shop and get it installed! It will perform! Trust me! Just get the straightest possible piping!
Heck, you live by me, we'll go together and i'll tell the guy what to make ya.
