    2013 Subaru Outback, 2.5L I have been deferring a P0420 code for awhile . Its on pretty much 24/7 now so Im moving forward on a cat/header replacement. The Walker cat is pretty much naked, however. OEM headers have nice shielding/cladding from flange to flange. Walker? Less so. Dinky shield...

    My 2013 Outback has about 118k on the odometer. I've had the dreaded P0420 on my dash for a few months with no issue. A week ago I was driving and started experiencing a shudder/intermittent power loss while accelerating. I was driving about 30 miles to Home Depot and over the course of the...

    I was driving my 2013 Outback 2.5i Limited (112,000 mi) the other day on 40 mile trip to Home Depot. Early in the journey I noticed my car shuddering a little bit and accelerating slowly from red lights. Once I got moving it accelerate better and I was doing about 55-60 no problem. About...

    I was told by my mechanic that I need a new catalytic converter for my 06 outback. I was wondering how important it is that I replace this? How long can I go with not replacing it?
  5. Engine & Drivetrain
    My 2014 Outback has about 185k miles on it. I took it to the dealership for the recommended maintenance. After that, I've had nothing but problems with it. Several times now, all the dash warning lights have come on. I took it to the same dealership and they told me the code indicated that it...

    '14 2.5i OB 78K miles Does this sound like a heat shield rattle, or is my cat breaking apart? I thought it was a heat shield again, but after tapping with a rubber mallet, I'm not so sure... If you think it's the cat, I want to get it to the dealer ASAP to see if it'll be covered under the...

    Hey all, Not a car guy and may post this a few different places so please forgive me if I leave out something pertinent or you see this posted somewhere else.. So I have a 2005 Subaru Outback 2.5L Limited, the CEL is on and is for the P0420 code. This is the only code the car is throwing. It...

    Hi everyone I took my 2003 outback into my usual mechanic for P0420 codes and he replaced the Catalytic Converter. Check Engine light came back on only two days after, so I ran the codes and got P0420 again. I cleared them and chalked it up to the new CC needing a few days. I am not noticing...

    Not quite sure where to start on this so please bear with me. I am going to lay everything out that has happened in the hope something important jumps out that may lead to a solution. The car in question belongs to my spouse, an original owner of a Subaru Outback (2004 base model, AT, EJ259...
  10. Problems & DIY Maintenance
    Even after replacing the catalytic converter and 02 sensors, the problem returned within 3 months. The CEL is on whenever the car is running. If I disconnect the battery to reset it, the CEL comes back on somewhere between 75 and 90 miles of driving. Odd symptoms: when key is in “On” position...

    Hi. I got the dreaded P0420 code with a check engine light on my 2003 Outback. Catalyst system efficiency below threshold Bank 1. Car does not want to go above 55---so probably clogged. Was wondering if anyone had recommendations on a good replacement. I found the one below on ebay....It...

    On Sept. 29, I got the following text from my local Subaru Dealership: "Hello this is ____ from Subaru Service just calling to inform you your vehicle currently has an open recall for the catalytic converter replacement if you can give us a call at xxx.xxx.xxxx will gladly get that taken care...
  13. Problems & DIY Maintenance
    I just replaced my rear Catalyic Converter as it’s called. ( one after the Manifold one) I replaced it with an aftermarket Walker 55585 Ultra EPA Certified Catalytic Converter. I know it’s always better to keep original but unfortunately some time ago when replacing the exhaust that rusted out...
  14. Problems & DIY Maintenance
    I have a Subaru Outback 2011 2.5 Limited which has been showing a P0171 Bank 1 System Too Lean code for weeks now. I have tried the following to fix it: replaced fuel pump with OEM Delphi pump/filter assembly; replaced the MAF; replaced both O2 sensors (before and after cat converter); replaced...

    Started to notice exhaust fumes inside the cabin at start up and louder than normal engine noise. Subaru dealer said catalytic converter was cracked and need to be replaced. Part alone was $1,500! Took it to an independent shop that specializes in Subarus for a 2nd opinion. They said it was...

    I've been having a lot of issues with my 2012 Outback 2.5 lately. Rough idle (has stalled a couple times from idle), real crappy gas mileage, P2096, a ton of rattling (probably the heat shields though), and rotten eggish smell. I've been told by several people it sounds like a catalytic...
  17. Problems & DIY Maintenance
    I have an 08 Outback that needs a new catalytic converter. The dealership said the honeycomb is breaking down in the mid pipe and so I have a few questions. 1. do the catalytic converters come with the midpipe as a whole set or do I need to buy the midpipe in addition to the CC? 2. any...
  18. Gen 4: 2010-2014
    Anyone replaced a catalytic converter recently? I'm getting quotes of $1500 - $2500 at dealers. 2011 Outback has just over 100k miles. It's not throwing any error codes yet but engine is getting quite loud and there is an exhaust smell in the cabin at start-up. Seems way too early for this...

    Hi all, first time poster, thanks in advance for your collective wisdom. 2006 2.5L 5speed Outback Test group: 6FJXX02.5NVD Been driving with the MIL on for the last 3 months, ignoring the P0420 I've been getting. As of yesterday, can barely make it up hills on the freeway, so I think the time...
