Anyone have any success doing secondary cat delete on STOCK exhaust?
i guess from past thread, there are only one sensor after the main cat before the secondary, so even u cut the secondary, the DME wont know its gone.

smog check via obd port will not notice it too, however, visual probably wont pass.
