Default Exhaust

I just had one question, i thought this weekend i would weld together some pipe and put it in place of where my mufflers had been. Would running straight pipes throw any codes, and or make my engine run bad?

No codes for cat back.

The only way to get the code is if for some reason your welds leaked.....

but if there was for some reason a leak, a code would be thrown?

Not quite sure how a code would come up since it is only going through a muffler and nothing else, but just wondering.

O2 sensors are very sensitive.
Ex: ECM-4201 is stored if the ECM registers that the rear heated oxygen sensor is switching too quickly. which can be from an air leak in the exhaust.

You should be fine...post up once your done.

BTW...are you turbo'd are NA?
NAs need some backpressure, which a cat should provide enough.

Oh...it will be loud. Turbos muffle the sounds a lot more than NAs. Did you take off the resinator and drive around to see how loud it is? You could staright will just the rear muffler removed?

Here is my dads BMW 540i with no rear muffler/ stock resinator and bullet cats:
