I'm just curious what kind of changes I'd see after I straightpipe the secondary cats. I'm sick of the American car burble and enjoy the smooth sound of the MB, so I'm going to try and keep that as much as possible.
I know that the exhaust will be louder, but how much? Would I hear more of a difference off idle or at topend? Are there any O2 sensors to deal with?
