Will All LT Systems Cause a CEL?

[Raptor626]

I'm finally ready to purchase LT headers and a full system, however, like many, I don't necessarily want to get a tune at the moment. Now, I know the issue here can be that since you're pushing the cats back, they don't have enough time to warm up in order for the sensor to read them. This inevitably causes a check engine light to come on.


Now my question is: Do all LT systems allow this to happen without a tune?

Nvm, I got it. Right here if anyone else is interested:

Since all LT's are approximately the same length and push the cats back to essentially the same place, common sense would say yes.
