question?

I have an 05 250 with a 6.0 and auto tranny. I have only installed an airaid intake on it. I was woundering if I deleted the cat and muffler if it would turn on any lights or cause problems? I dont have it chipped or reprogramed.

thanks for any info

That should not cause any problems at all. Well initially it might cause i decrease in fuel economy because you are a little harder on the pedal to hear the new sound lol

No, you won't get any check engine lights. Had mine done and never had a problem.

You won't get any CELs or problems.

But, like said above, it might decrease MPGs for a bit cause you'll LOVE the sound!!

Only had lights flashing when I was caught speeding

Hope it doesn't happen again!
