I put my exhaust and off road xpipe on my 06 GT a month ago and a couple days later the SERVICE ENGINE SOON light came on and is still on. I was thinking it's prob cause I have no cats, but I wanted to know how to get that light to turn off?

 

The O2 sensors are thowing this code. You disconnected the CATs right? No CATs, no O2 sensors.

 

So is there anyway I could get that light to turn off somehow?

 

I am not so sure now. I think Sherwood is right, inexpensive method too.

 

MIL Eliminators

Or a custom tune

 

I have the Steeda MIL eliminators. They were $60 and i got them from brenspeed. http://www.brenspeed.com/mustang_2005/midpipes.htmlJust scroll down a little and they are there. grandted they are more expensive then from mileliminators.com but you don't have to cut any wiring. they use the factory plugs

 

I have MIL eliminators on my stang and no engine code for the past 8 months!!

 

If you plan on buying a cai /tuner in the near future then wait. Let the tuner know that you have a o/r x-pipe and he will turn off the rear 02's and make any air/fuel adjustments that he feels is needed. If you don't have plans to buy a programmer then mils are your best option.

 

It could be many things, and may not from your catless system. Find somene with a scan toll and find out.
