Hi flow cat=money..and another thing to go bad eventually reonator delete equals 5 bucks for pipe and 3 bucks a peice for 2 clamps....BUt that is nothing i would do as its not good to modify exhausts away from the standards for an exhaust to keep it clean and quiet....

without the resonator your car will sound about as tin like as a ricer, go with the high flow cat such as this one http://performance-curve.com/3goerli...dii608227.aspx

The cat I was looking at was by Magnaflow. Good or bad?

My magnaflow is a good 3 years old. No problems. A hi flow cat will deepen the exhaust tone a bit, as well as open up the flow a bit. Removing the res will make it raspy. Mine is still on. You can also go with a larger res for better flow.
