X-PIPE Off Road Exhaust Question

Discussion in '2005 - 2009 Specific Tech' started by blk05stang, Jul 26, 2005.

  1. I was just curious.....those who are running off road exaust (no cats) are you using mil eliminators or are you tuning around it? Is your check engine light even on? Let me know because I am running an off road X and I think I am getting some ugly codes due to my exhaust. If you would please post your exhaust set ups and let me know how it's doing? Thanks
  2. I have yet to see any MIL eliminators for the 05's so I think you have to use a tuner to turn off the back two O2 sensors or you will get an SES light turned on.
  3. I've got the mac pro-chamber on mine w/o cats and all I had to do was tell my tuner ( JMS) that I put it on, he emailed me a file to turn of the rear o2 sensors and no problem.......nice pickup in get-up and the sounds now AWESOME!!
