well my cat sounds like a stock 4.6 stang
your left cat has no 02 sensor so you can either gutt it or replace it with a pipe, now on your right cat which is the one under the passenger side, has an o2 sensor, so just unhook the o2 sensor bring the cat down and gutt it, then just put the o2 sensor back in and walla!!!but be extra careful when your gutting the cat that you dont mess up the o2 sensor.If you break it you will need to buy a new one, and they are like 70 bucks. Your engine light will not come on, mines hasnt and i gutted my cats about 6months ago. you do loose a bit of low end torque, but if your doing it for the sound then you'll be alright.
