help on a performance mod
Ok, I drive a 96 LS with an ATX. I am looking to get a new converter for my car. I was thinking test pipe. But i have been told that there are O2 sensors for the Cat. Is this going to be a problem? I did a search on this but never really found too much that would help me. Also, what are the measurements for the High flo cat or a test pipe. What is the diameter of the stock exhaust? how long is the Cat? Any and all help will be greatly appreciated. Thanks all.
