The cheaper 12 month warrenty cats are only designed to last 12 months. Disposable cats. The contents of em are waaayyyy inferior to the genuine or OE counterparts. I usualy sit em on 3k for 5mins before i test em and as its setting up if it struggles to go through 1st time. Got any leaks on your exhaust? How many boxes?
