Today, I added Flowmaster super 44's, installed an x pipe, and had the resno's taken off. The sound is awesome! The guy added straight pipes where the resno's were and welded back the tips. All for around 500 bucks. The system is so unrestrictive now and it has that low mean growl at idle I wanted. Lots more power and you can feel the thunder under your feet when you kick it. The back end almost got sideways when I punch it on a back road. I highly recommend this set up if you're on a budget (like me) but want a nice upgrade for less.
