By installing our Circuit Werks High Flow Cats, you will not only improve dramatically the sound of your Boxster, but you will also gain the horsepower since it's not restrictive anymore where you would normally drive the car. Like to a local car meet, to work, or weekend cruising around town.  The sound will be slightly louder since your cats are deleted but once you step on it, you can hear the deep sport tune and depending on the exhaust you have.  Comes with a limited warranty from the purchase date.  Brushed Finish stainless steel, all are hand built to meet our high quality standard, then T.I.G. welded together.
