Does the use of downpipes without catalysts on the Meisterschaft 90mm system make an ECU tune a mandatory requirement, or can the car run fine without the catalysts and without adjustments for altered fueling needs? With no catalysts I assume there is no need for the flapper valves on the mufflers? Is there a way to defeat a warning message on the display when the catalysts are removed?
