    Will these work with factory headers and factory mid pipe? If not could you put a link with ones that will, if there is any on the market? Please and thank you.

    • These would not work with the factory headers and mid-pipe and we currently would not have cat-deletes for this year car at this time.

    Currently have the BBK catted x-pipe. Will these work together with that x-pipe so I can get rid of the cats? These are 3” and I believe the x-pipe is 2 3/4”.

    • The MAC Off-Road Cat Delete Pipes will not be compatible with the BBK X pipe.

    If the 02 sensors will hook to these can I use a sct tuner and just shut the back o2 sensors off and do these reqir any welding

    • An SCT tuner or other handheld tuner will allow you to turn off the O2 sensor banks which will eliminate any light flashing on your dashboard. You will simply need a new tune written for the new Cat-Delete pipes. The MAC Off-Road Cat Delete Pipes involves a direct, bolt-on process. The pipes can be installed seamlessly with clamps to avoid cutting or welding.

    These delete cats what about 02 senor placement

    • The MAC Off-Road Cat Delete Pipes will not delete the oxygen sensors. They will go in the factory location.

    Can these be used in conjunction with with the MAC pro chamber cut clamp, to make our own off-road system?

    • The MAC Off-Road Cat Delete Pipes are a direct bolt on to the stock suspension, so we cannot guarantee that they will work with any aftermarket parts.

      DID NOT FIT!!

      did not fit at all it was way too short and on top of that after my mechanics extended the pipe by adding more it was bent on one side so they also had to fix that to much of a hassle

      Not good at all!

      Extremely disappointed with these pipes. They do not fit my 06 GT and had to take it to a muffler shop to have it installed. The pipes are not bent enough and both sides comes with only one hole for the O2 Sensor when the passenger side has two sensors. Not only that AM advertises delivery in 3-5 days and I only got it 10 days after! I expected more for a $115 piece of metal.
