No, due to the oil pan. It will fit in the impreza oil pan if you get the smaller one.
If it's a two, then yes. 5 cylinder SOHC engine
It was designed to fit a 2009 Outback, but it could also fit a 2010. Except for the ones near the flange where it meets the engine block, some of the heat shield bolds retract. I had to cut the heat shield with tin snips near the flange where it connects to the rest of the exhaust to make it fit. The rusted bolts on the heat shield had to be drilled out and replaced with stainless bolts purchased at Home Depot. It works perfectly. P0420 is no longer available. It's also a good idea to replace the O2 sensors at the same time.

This bolts up reasonably well (though not perfectly), comes with inexpensive hardware (studs are cheap, nuts are even cheaper), and solves the o2 sensor code, as others have mentioned. br>br>I can already tell you that the product page contains some misleading information. The catalyst is not supported by a metal substrate - Ceramic is used. It also has some fairly thick welds on the inside of the inlet ports, which may limit exhaust flow slightly (though this isn't a major issue). If you want to grind them down, go ahead, but it's probably not worth it. br>br>After a few months of use, the catalyst on my last Amazon exhaust manifold broke apart. I expect the same thing to happen here, but I'm hoping it will last a little longer. When it happens to me, I'll post an update. (I replaced all associated emissions components, including both o2 sensors, plugs, wires, coil, air filter, PCV, even cleaned my MAF sensor and had the injectors flow tested and cleaned, as well as replacing my fuel filter and pump strainer, and I also replaced my thermostat with an OEM unit - The head gaskets *might* be leaking a *tiny* bit, but this is unlikely, and the compression numbers are within specification).
There isn't a code for P0420! Dan B. After receiving the PO420 code on my 06 Subaru Impreza, I purchased this. The code would not go away even after I replaced both O2 sensors. I bought and installed this catalytic converter, and now I don't get any codes! I wish I had replaced this sooner! When I removed the old converter, I cut it open and discovered that it was completely melted inside, restricting exhaust flow and resulting in the code. This converter was exactly what I needed! It was a cinch to install! The only issue I had was that the heat shields on the original converter did not fit perfectly on this one. I was able to adapt the original heat shields to fit over the new catalytic converter with some creative grinding, and it now works perfectly!.
On my 2008 Outback, I had a plugged catalytic converter as well as code P0420. This cat fits perfectly, the light went off, and the rear O2 sensor graph is a constant line at 0 on acceleration, making it dangerous to drive. Rather than going up and down, the voltage is set at 7V. Acceleration is back to normal; it's still a slow car, but I was used to it being even slower with the bad cat, so this is a welcome improvement! The cat was bouncing around in a box, and the gaskets were just thrown along, so I deducted one star for poor packaging. Where the loose cat and studs/nuts bag hit them, they got some nice bends and creases.
I wasn't able to repurpose all of the old heat-resistant materials. You'll have to find something else to do with the shield, or use the half that can be transferred. Also, when I turned the car back on, the new unit smoked for a short time because it came with some oil on it from the factory, but that quickly burned off, and it's now working perfectly.
I replaced it with this, and it works great! Let's hope it lasts a long time!.
It was as if they were made for each other. We had no problems removing the old one and replacing it with this one; however, we wanted to use the old heat shield on the new exhaust, which caused problems. We had to cut off rusted bolts as a result of the problem. The heat shield fit well over the new exhaust, and we replaced the O2 sensors while we were apart. After driving for 50 miles or so, the vehicle passed the emissions test. I would buy it again.
A 2009 Impreza with 97k miles was purchased in late August of 2020. Two Denso O2 sensors have been installed. After only 17 months and 9,000 miles, the check engine light returns with the P0420 code in late January 2022 at 106,000.
The fit is almost perfect. The pre- The o2 sensor mount for the cat was welded in two inches closer to the original. To get it to fit, I had to cut out some metal from the heat shield, but it all worked out in the end.
