Ill bet that the 175 high flow is cheaper than a stock cat at the dealer, not for sure though.
600 bucks for a stock cat from the dealer. If you don't live in a SMOG controlled state, I highly recommend you get a highflow. 175 for the carsound is even high. You can get a universal cat for less than 75 bucks.
As far as the DC Sports header, you have to watch out. They've got the 4-1 and the 4-2-1... and they've also got a "JDM spec racing header" that is essentially a JDM Type-R knockoff. Being such, it requires the same equipment that the Honda header requires.
