I am removing my cat from my exhaust. I have an 01 eclipse gt spyder. The car comes stock with 2.5" exhaust piping. Well i can't find a shop to do it if anyone knows of one let me know. My question is my friend told me about something called a test pipe that comes with the welding already done and a cat delete or whatever he called it. Just wondering if anyone had anymore info on this thing? And if I remove my cat wat do i use to replace my O2 sensor to keep from throwing a code?

Any help is appreciated thanx everyone
