Yes I know it's illegal to drive without a cat and won't pass emissions, but is it safe for the car? Some people told me that it might hurt the car without a cat. They weren't sure but I just wanted to check as well cuz I don't want anymore problems =P I have a 98 CSVT. The reason is, a piece of the cone or whatever in the cat broke off and stuffs still floatin around in there and a huge peice went up throught the exhaust pipe but couldnt get around a bend. Noticed it after the pipe where one of the claps was rusted and broke right off =| Ya that was fun. But what I want to do is just replace the cat with a straigh pipe if possible, for the time being while theres about a year left b4 emissions.
