Just got the car running it had been sitting close to a year.I have put around 100 miles on it. I got on the gas for the first time and it started to make some noise a bit after that. The inside of the drivers side cat is shaking inside like a dog trying to sh-t a peach seed. The exhaust manifold is not making noise and the pipe to manifold is tight, i probed it with a noise scope. Can you run a SC with no cats, will it effect anything on these cars. I am new to the SC world. What is the best and most thrifty way to replace them or just remove.
thank you Mike
