Flowed out

[JAVZCOBRA]

Need you alls expert advice on my mufflers. This morning I installed 2 chamber Flows on my 98 Cobra. I did not replace or cut out anything else, just replaced the mufflers w/ Flows. Now all of sudden my CHK Engine light comes on. I have heard of this when u cut out the CATS, etc....but not when you simply replace the mufflers. Now what?? Please help?

Check your O2 sensors maybe. My car said "Check Engine" for a while after the cats "got stolen" but now it doesn't say anything :thumbsup:

My car is a 1990 Mustang, so it may not be the same for me. I guess it would be about the same though, 'cause it's only the exhuast. I hope this helps at least a little

Did you nudge or bump the O2 sensors by the way while you were under there?

That is really odd........I can't think of what code would be thrown by just replacing the mufflers. I had Flows welded into my catback without a problem.

I would disconnect the negative battery cable for like 15-20 minutes to reset the computer and then see if it comes back on. If it does, go to Auto Zone or something and have them pull the code for free and tell you what it is.

Disconnect your neg. battery terminal for 15 minutes. That will clear the code. See if it comes back. Might have just been from welding on the pipes.

It's probably just a coincidence. Changing mufflers would not through a code, there are no sensors down there that far.

Hey guys, thanks for the responses. Since I posted last, the "chk engine" light hasn't come back on. Lightning Larry was probably right about the welding thing.... Btw, just w/ the FLOWS it sounds awesome!! I was real surprised that it sounded that good w/ only mufflers.
