i've heard that the WRX can pass emissions w/ 1 working cat (car has 3 so far)

i doubt the VISUAL inspection would go over too well though ;)

but as far as smog, i think you'd be fine since the car is a low emissions vehicle in the first place

Thats what I heard too, that it'll pass with just one cat. Someone I used to know just put the cat back on when it was time for the test, then he took it off. Its fairly simple.

in maryland they just started to do obd 2 testing besides the all wheel drive treadmill test....i'm guessing they will be able to tell if anything is missing...it doesn't sound feasible to add upipe then remove every two years..anybody know about this?
