upgrading exhaust system

11-20-2007, 02:36 AM
My fellow Probe fanatics ... I wish to upgrade my exhaust system with performance parts but, do not want to put any attention my car (avoiding notice by the local police). I've been told that Borla mufflers provide good airflow but, is very LOUD. Can anyone recommend a descent exhaust system that provides extra horsepower without the increase in noise. Your help would be greatly appreciated.
