Is my Car a California or Federal Emissions Vehicle

No Tools Needed
1. Determining Your Emissions Specification
Open your hood
Locate your catalyst sticker
If the sticker says "This vehicle conforms to California regulations," you have a California emissions vehicle
If the sticker says "This vehicle conforms to US EPA regulations," you have a federal emissions vehicle
If the sticker lists both EPA and California regulations, you have a California emissions vehicle
Hi, I'm Mike from 1A Auto. We've been selling auto parts for over 30 years. We're dedicated to delivering quality auto parts, expert customer service, fast and free shipping, all backed by our 100% satisfaction guarantee. Visit us at 1AAuto.com, your trusted source for quality auto parts.
Determining whether or not your vehicle is a California emissions or a federal emissions vehicle is pretty straightforward. To do this, you'll want to locate your catalyst sticker under the hood of your vehicle. It'll either be actually on the bottom side of the hood, most GM vehicles have it on the air box, and other vehicles may have it along your radiator support at the front of the engine bay.
All you need to do is see, "This vehicle conforms to California regulations." That means that this vehicle is a California emissions car. Just because you're not in California or are in California doesn't necessarily mean your vehicle will be one way or the other.
Now, our F150 has it down here on the radiator's support, right at the front of the engine bay and you can see here, "This vehicle conforms to US EPA regulations." This means that this vehicle is a federal emissions.
Now, here we have two things that are a little different. Our catalyst is located on the vehicle's air box and this vehicle conforms to US EPA regulations and California regulations. If it conforms to both federal and California emissions, it's considered a California emissions vehicle.
Thanks for watching. Visit us at 1AAuto.com for quality auto parts, fast and free shipping, and the best customer service in the industry.

Goodd price. No problems so far.

February 16, 2017
Installed it about 6 months ago. It hasn't had any problem since installation so far.
It does not come with the replacement attachment bolts which will most likely be needed since the bolts on the old catalytic converter will shear off during disassembly. Recommend getting the bolts from Subaru since the rear bolts are shouldered and should to be a specific length.
Also, make sure to tighten the bolt that is installed on the cat converter for the third sensor provision. It came installed on the pipe but it came loose and flew off not too long after it was installed.
Great Service, Great Prices

Your service is great but I would like to correct something. Your so-called Converter is Not a Converter but it is called Resonators.. A Converter comes before the two, on the exhaust system. I returned the Resonators because they were not the problem with my car. The problem was two oxygen sensors gone bad. I will definitely keep your company in mind for another order, in the future.

The shop charged $100 for the install. The car actually runs better, presume the previous replacement converter was clogged. This one is guaranteed for 5 years. Previous only 1 year. Happy camper here. Total cost $350, local shop wanted $1,000.

Put it in with ease. (Dont forget to makeshift the old heat shield on the cat, or your floor board will feel a little toasty). It cleared my p0420 and looks good. Dont forgot also to order a new tranni mounting bracket from Subie if yours is broken. I stress this, u need to mount it. 100% great purchase
Very well made

The cat is very well made, went on pretty easy, and got rid of my CEL. My only gripe is that I wish they would include some mounts for the OEM heat shields. They can be transferred but requires a little rigging, other than that its great

Fits 03 Outback, makes Orange Light Go Away, OCD Tendencies Can make install more difficult

It fits and it cleared the P0420 code. I opted to try to put the factory heat shields on it as I figured it rolled out of the factory with those on it for a reason. This is where it looses a star, the heat shields do fit, mostly. They can only be secured around the new cat via their flanges but its plenty enough to keep them from rattling and there is distance between them at the cat, so they still work. The hole for the leading O2 sensor is lower in this cat than the factory one so extensive dremel modification of the front heat shield is required to fit it. It also comes with the gaskets, which is helpful, you will need spring bolts and they Y-Pipe to cat bolts, as it will be unlikely they will survive the removal experience.
Fit perfectly

Great product fit perfect
Quality product after some modification
Daren
December 8, 2021
It fit right in, but the heat shield did not fit exactly over it. There was quite a bit of trial and error in modifying the heat shield to fit, but I was able to get it done. You have to be ok with cutting and modifying things to make this part work. Once it was in, all was good.

When new o2 sensor doesn't fix p0420, you need a cat, and I've fixed it many times..For 300 bucks you can't beat this bolt on cat. Subaru wants 1800 for a new one. 1A auto comes through with fast, quality delivery.

As I recall, p0420 was the code that our 2003 outback was throwing and it has yet to throw it again after installing this cat. Be aware, I had to do considerable alterations to the OE heat shield in order to get it to fit back on, but once I did, all has been good since the install. I would recommend.
