Hi, any idea if I take out the cat exhaust system from the original setting would it effect the ecu? Any different on the performance or the sound? Or can I replace to those after market mid box.

it been put there to filter out all the hazardous gases before release to air. some say got improvement. i never test it out. i just replace mine to after market. get better FC than original cat. as i know all car using ecu advised to set back the ecu for better performance.otherwise just wait the ECU auto learn your new upgarde. please do correct me if i was wrong.

Wsonny,

have you tried tee golf mode? they purposely jam up the exhaust flipper to let it open all the time and louder than stock setup if not mistaken...not worth to remove if your exhaust still standard...JMO
