Starting Sept. 1st, Missouri will no longer require emissions inspections on cars older than 1995, so I have a quick question for you guys.

Has anyone removed the catalytic converter without any other engine mods? I'm sure that the US version of the S38 was designed to work with one and I'm just curious as to what would happen if I just ran straight pipes from the header to the muffler. Would that freak out the ECU?

Thanks in advance!
