OBD1 or 2 refers to the type of On Board Diagnostic system. OBD2 has been mandatory for about 10 years or so and monitors more stuff in greater detail than OBD1. It also has a standardized connector for a scanner whereas OBD1 may or may not have a connector and is not standardized very much at all. With OBD1 typically you must dig out the computer from under the seat or wherever and then watch some lights flash. That tells you nothing unless you have the information to interpret them.
You car is OBD1 and the only good thing about it is that items like O2 sensors are simpler and cheaper than those for OBD2. You just have to buy the appropriate parts for your model and year and they will have the appropriate functionality and connectors (if required). I'm sure others will correct me if I'm wrong but I think a cat is a cat and the only requirement for your car will be the physical fit. Any muffler shop can provide one for you and I doubt if brand makes any difference. The sensor you can get from Subaru or most after market suppliers, and replace yourself if you are handy with wrenches and stuff. It probably has only one or two wires, unlike my 00 OB which has four.
I'm not sure how you propose to disconnect the cat. If you mean replace it with a piece of straight pipe I'd be surprised if the car ran better unless it has collapsed internally and is obstructing the exhaust flow.

Just got a new Legacy GT and have heard some after market upgrades are avaliable I'm interested in handling performance first ANY IDEAS on first steps and/or recomendations ??
Lose the OEM tires.
You can go to a site like LegacyGT.com and learn what aftermarket swaybars, springs, coilover shocks, harder bushings, and other things can be done so that the vehicle will handle better, at the expense of thousands of dollars and terrible ride quality.
The best return on investment would probably be from Skip Barber.
#5908 of 8644 Hesitation 2005 Outback 6.0
Mar 04, 2006 (11:51 am)
This Outback performed beautifully for about 4 weeks when new, then started hesitating when the pedal was floored starting, coming off a ramp or passing. It's worse when engine is cold, but persists when warm, and more hesitation in colder weather. Happens with high test or regular fuel. Took it back to dealer, who re-flashed it, and it did well for about 2 weeks, but now back to hesitating. Back to dealer again and Service rep felt it, but said it was "normal" for this to happen because the transmission was learning and takes time to make a decision about which gear to choose! Now has 13000 miles and clearly hasn't "learned." Hesitation is about 1 second into first downshift, then about 2 seconds into the next lower gear downshift, and then it takes off fine. Any thoughts on getting this fixed?

Brian filled in the info about OBD1 & 2 systems. I have a laptop package for OBD2, and you can really learn a lot about how things work by watching a bunch of different functions graph at the same time.
The newer cars have O2 sensors with multi wires because they incorporate quick warmup heaters and other functions. The older cars were often just 2 wire. The parts counter will give you the correct one for your year.
My suggestion about removing the cat was only to help diagnose if the present one was clogged to the point that it was restricting flow & causing driveability issues. If not, put it back on. If it is, replace it. I value the air we breath very much, and do not advocate permanent removal the cat.

Hello Linda. My wife and I also have a 96 outback and we are experiencing the same issues. We also had plugs and wires replaced and it addition had Oxygen Sensors replaced and we still have the same issues...Car stalls when cold and going up hills...Loss of power followed by engine shut down. If you've had any luck lately please pass on the advice.
#5911 of 8644 Check engine light
Mar 06, 2006 (10:32 am)
My 2000 Outback 82K has had the check engine light go and off for the last month or so. It seems to come on for a day or two and then go off for a week or so, probably done this about 3 times. It turned out coincidently I had a dealer visit just after the first time. The dealer told me not to worry about it since it turned off. I should note that I have been carefully checking the gas cap so that is not the issue and my car passed the emissions inspection when it was at the dealer.
Any thoughts? should I be concerned about this?

If you decide to 'lose the tires' and go so far as to get different wheels...let me know. I am looking for a set of GT wheels to put on my 01 LL Bean outback.

Have you tried replacing the mass airflow sensor? My '96 was having a stalling issue when I first purchased it back in Aug '00, and while I (nor 4 different dealers and/or mechanics) was never able to diagnose the problem definitively, the last mechanic suggested that I *try* the MAS. I purchased a used unit and had it shipped up from Seattle. I have never had a stall since..... ?
Oddly, while the CEL would illuminate each time it stalled, no code was recorded. Maybe I just got lucky.

You could go to a dealer or just about any decent mechanic shop and get them to plug in a scanner. Even if the light has gone out the record stays in the computer for a while afterwards.

Some suggest rolling into the throttle gradually. See if that helps.
