that articale has some good points and bad points.
Almost all the tuners I have been talking too really are pushing off road for the HP levels this car can achieve.
They say the aftermaket quality is just not on par with the OEM and once you reach 650-700bhp which is really easy to do with these cars it is not worth the risk. Even the the aftermaket cat has a higher cell count they cant still plug and fail.
Now many people run them but depending on how hard you drive you car it is food for thought. I have seen one person on this board kill JBA cats alreay on a single track day.
Honesly without some kind of CFM numbers the argument of a HIGH flow cat is just a marketing statment. Even if a cat has a HIGH CFM flow if it is made in china out of inferior materials it can still fail.
