I been lookin at de catting the up pipe and down pipe on my car and ive been told different things ive told if de cat it i will need a re map as there is a sensor in them and then some one else has told me i dont need to. so is there any one on here that would tell which one is right.

thanks

The sensor is the lambda sensor, and AFAIK it's in the cat pipe, not the down pipe. You can certainly decat the up-pipe though. Won't give you any extra power though, just help spoolup. Decatting the downpipe will help though. Assuming I'm right about where the lambda sensor is (get under the car and look for a couple of wires coming out of the exhaust somewhere near the front) then no, you don't need a remap.
