Replacing catalytic converter?, Doing a full exhaust system Options

[Legit94GT]

So i have been told something different from every shop i've talked to now and am getting a little fed up...

So some shops have told me that i wont need to buy a new catalytic converter
Others say they will inspect it and see
And the rest tell me i will HAVE to have a new one

So for anyone who has done an exhaust system if you could give me your two cents on the matter it would be really appreciated:)


car is in perfect running shape, and has 90xxx miles on it...

Hey man, are you talking about your top or bottom cat? I'm guessing your talking about the bottom since you want an exhuast. You shouldn't need it, they'll just have to add a bung for your second O2 sensor on the pipe after that area. Honestly you're not going to see any gains from removing it, I would just recommend getting a high flow cat for down there to help gaurantee that your second O2 sensor receives the correct readings and maintain legal emissions. Of course you could just have them make a delete pipe for you that way you can add a cat later to pass emissions and then remove it again easily. They have to add that bung for the sensor after that section anyway.
