i have 2004 4.6 if i cut out rear cats will the light come on .are wahet can i do to keep it off .and what will it do far mpg. i have oder a eage will it help keep light off

 

The CEL will come on. Get a custom tune OR install MIL eliminators to shut it up.

P.S. Your typing/english is not the best

 

Just got my MIL eliminators hooked up. Got them from I think RPM. If you do order them from there, only order 1 quantity. I ordered 2 but they didn't say that they came in packs with 2 in each. Now I gotta return 1 pack...

 

thanks

 

Is it strange that I drove 4 days after my rear cat removal and my check engine light never came on? I know it does work. I still got the eliminators just in case though

 

tune it
