Will putting a 4" turbo back exhaust system with cat delete through a CEL?

Shouldn't throw any codes. :thumb:

That was what I was hoping to hear. The reason I asked was because the guy at the local exhaust shop stated I would through a CEL because the system would not have enough back pressure. And the EGR would not function properly, resulting in a CEL.

actually from what I understand there is some truth to that (on 6.0's), the egr/vgt system or something like that but it isn't a very common problem...... I would not worry about it too much :thumb:

I was told that it can but not will.. Haven't seen one yet with my straight pipe .

It may through a code but no CEL on the dash.

I see that you is a regular member. If its such a problem why don't you become the first Powerstroke spelling enforcer member.

I would but it won't let me since I'm not a premium member anymore.
