It's gonna be personal preference just like all the other threads. If you get some good reply's make your decision based on your own preference and research it a little for yourself before you make your decision.
IMO there are better systems out there to choose from. Again, personal preference. My choice would be:
[Equinox] Install: GTM 3" Cat-back Exhaust
Especially if you plan going turbo in the near future. I would also add HFC's for power gains alone. Test pipes if you don't want your ear drums anymore
Good luck OP with your choice.
