Ok i am getting a GReddy Sp2 for a 99dx, i have a 00ex will it if it i just cut about a foot out of the pipe? Something is wrong with my 02sensor on my cat is bad. I need to see if i need a new one or just the wire unpluged. How much is a new sensor? Where does the wire from the 02 sensor go to, so i can see if that end is plugged. Thanksfor all the help guyz!!
