off road pipe

[ranton08]

k i got a 2005 mustang gt with a cold air intake, throttle body spacer, and a Diablo sport tuner. i know some one that will bend pipe for me and i was going to take off my cats. i was wondering if i have to plug the three wires back in? and will i need to decrees the amount of fuel so i don’t run rich? i have heard that with the cats off the car will run rich and i know i can play with the air/fuel mixture with the programmer i have.

I would suggest just buying an off road x pipe. They are cheap and a fast install done in the driveway rather than hack your stock piping as you might need it one day for inspection or some other reason. You need you 3 O2 sensors but the rear one must be turned off via you hand held tuner. Most tuners do that so if you already have a tune I'm sure they are already off.

yeah im not going to cut up my stock pipes its just that the guy does exhaust work outta his barn and he is a good friend of my dad and said that he would bend it for me for free. but i just didnt know if i had to put the sensors back in
