Downpipes + stock exhaust = damaged 2nd cats?
Is it true that the 2nd cats aren't strong enough to clean emissions so therefore running catless downpipes with stock exhaust will destroy the 2nd cats?
I hate the smell of catless so I was thinking of running downpipes with the stock 2nd cats.
Can you guys chime in? How many miles on the car w/ catless downpipes and stock 2nd cats?
