Ok, so I am going to ask the question... On the 370z the stock cats have two cells...one which is monitored buy the a/f sensor and rear 02 sensor..after that there is a cell I would refer to as a clean up cell... has anyone removed this? any gains noticed? obviously u would not get a MIL cause its not monitored.. just curious... the main stock cell is small in size and I feel if u removed the secondary non monitored cell it would probably be equivalent to a high flow cat? ... this is just theory..if anyone has tried this, please let me know.
Thanks Tim
