How are you Eh!

 

I now have about 12K (KM) on my 97 Outback LTD with EJ22 Engine (95 Auto). Only hiccup I had was after a while it threw a knock Sensor code.

I R&R'ed with a new one (ordered from a foreign country of course). Anyhoo, what a difference with the new knock sensor, runs very smooth. The old sensor was physically cracked. This Car is best rig I ever had.

 

Just about to slap on my Yokahama Snows. Let her snow. Looking into aftermarket exhaust. My Cats are questionable (came off a 98 Outback blown h/g). Can I guy bolt on a nice exhaust and simplify the cats so that the engine breathes better and still passes emissions? Any advice on exhaust sys?

 

Thanks

 

Doogymon

 

So your question is about replacing the cat?

Well, I have seen "hi-flow cat's" before in cheap auto shops and online, but have no idea if they are any better. To pass emissions in some countries you pretty much need bone stock. Not sure about Canada. Best bet might be to ask a exhaust shop.

you'll have to ask locally about local emissions laws. around here so long as a catalytic converter is on and functioning properly it will pass. i've had very very old converters and larger aftermarket hi-flow jobbies pass just fine. tried once without any converter and did not pass.

 

exhaust changes don't affect anything around here, so long as a converter is somewhere int he mix. i've done tons of stuff to mine, always passes except the one time i didn't have one!

 

but even around here each state has different laws, some areas don't have emissions at all, some don't allow exhaust modifications...etc.
