I know that the ecu will accommodate the changes of intake filter and exhaust pipe but I was just curious about the cat delete. The G56 ecu is unlocked so I bet it can do just about any mod you desire, but the OEM ecu was my question.

We don’t have pollution checks where I live so not particularly worried.

Just want the machine running coolly and smoothly.
