performance CAT
 

Will all aftermarket cats pass emissions?

Im looking at a magnaflow performance cat from automotive-warehouse....will it pass emissions?

mine did.

yes it does, for sure.

keep in mind a lot of cats need to changed after specific mileages

if it wouldnt pass emissions, what would be the point of selling performance cats be in the first place instead of just replacing it with a straight pipe?

Because under a visual roadside inspection its illegal if you are missing your cat. And highperformance cats are generic meaning on certain cars with less strict emmission standards they may pass fine where as when you install them on another car it may fail.

oh and you might have to get new o2 sensor if you have one on cat.

DOES THE 92 DX HB HAVE A O2 ON THE CAT?

nope....EG's only have 1 4-wire o2

I know that they have the 4-Wire o2, but I always thought there was another one? :shrugs:

because when I went to look for an o2 for my car he said that there were 2 different ones, one for the front and one for the back or whatever... and the one for the front was a lot cheaper...anyways still looking for one dont' want to buy an expensive one, not keep this engine for long

nope, just 1 in the exhaust manifold.

SAWWWWWEEEET

OBD1=1 O2 sensor, OB2=2 O2 sensors

thanks :D

i've seen many of these cats fail emmissions where the stock one did

did? or didn't?

I'm pretty sure he meant didn't.

ye i passed


how come OBD 0 = 2 o2's :p ( at least on mine )

i stil have to get my emmission done next year, but i have no rez.

so no rez, megnaflow hi-flow cat, what do you guys think will i pass or not??
