  1. EJ25 - 2.5L Non-Turbo (1998-2010)
    Hello, I want to put UEL headers on my car but also have a cat on my car still. I have a non turbo 08 Forester. Has this been done before or is it not even worth doing. I honestly just want the subi rumble without the turbo. (but still be legal) If this hasn't been done before how did you...
  2. Engine and Exhaust
    Hi, I have broken the flange on my catalytic converter, a rock hit it and it broke. The exhaust is blowing, and it is very very loud. I want to get it replaced. It is very rusty too as its the original oem from 2004 so there isn't much material to weld it back together. No CEL have come up...
  3. EJ25 - 2.5L Non-Turbo (1998-2010)
    Non-turbo, 2.5L forester started running very rough, dead mis-fire two cylinders. Shop replaced spark plugs and wires, sent us down the road. 90 miles later CEL and multiple other lights on dash lit. Took it to hometown shop, they said bad converter, sensor or two also bad. Replaced that. Drove...
  4. EJ25 - 2.5L Non-Turbo (1998-2010)
    I have a 2009 Subaru Forester. I was wondering if it's possible to take the catalytic converters off a 05 Subaru Outback, and have a muffler shop use them on my 09 Forester. I only need one cat I don't see myself using the car for more than a year and I can get the catalytic converter for free...
  5. EJ25 - 2.5L Turbocharged (2004-2013)
    The O2 sensor on my 2009 Forester XT (turbo) just went bad, and neither the dealership or a muffler shop could remove it (rusted in), so they are recommending that I just replace the front catalytic converter. Apparently, in the turbo, there is both are pre- and post-turbo catalytic converter...
  6. EJ25 - 2.5L Non-Turbo (1998-2010)
    Hello! I've perused the forums looking for a solution and I've came up short. I also have very little working knowledge of repairs and advanced car repairs. My 09 Forester has around 130k on it and over the past few weeks I've had some issues with a P0420 code. I have a persistent code reader...
  7. EJ25 - 2.5L Turbocharged (2004-2013)
    Hello all, first post here. I recently bought a 2009 Forester XT from a dealership and about three weeks after owning it the turbo went, taking the cats out with it. The 3rd party warranty from the dealer covers the turbo replacement, but not the cats. I have found a used STI exhaust of the same...
  8. Engine and Exhaust
    I recently bought a catalytic converter for my 05 Forester X and when I got it I noticed that it didn’t match the picture (heat shields are missing). Will this be okay to install? I have seen people installing similar catalytic converters without, I just want to mainly ensure the cabin/ floor...

    Subaru codes: P2444 P1410 P2431 I have an automatic 2006 XT Limited (turbo) forester. Recently "Sue" lost acceleration power going uphill and sputtered out on me. We got her towed home. Changed the busted spark plugs, cleaned mass air flow sensor and tested it, and have been looking her over...
  10. Engine and Exhaust
    I'm reading that theft of catalytic converters is on the rise. Does anyone have an anti-theft device installed? There's something called the Cat Clamp that is like a big cage around the converter. Was wondering if anyone has one of these. I have a 2016 Forester (non-turbo).
  11. General Troubleshooting and Technical Help
    I replaced the OEM exhaust manifold in my 2009 Forester with an Eastern Catalytic Manifold from Rock Auto. Had the install verified by my mechanic. After about 200 miles the P420 code came back on. Mechanic states that the rear O2 sensor reads all over the place while running, 100mV - 1000mV...
  12. General Troubleshooting and Technical Help
    My Subaru initially had a California emissions catalytic converter. The converter now needs replacing and I was wondering if it would cause an error code if I replaced it with a non California emissions catalytic converter. Any experience?
  13. General Troubleshooting and Technical Help
    Greetings, I have a 2009 Forester 150k miles that throws a P0420 code, it happened 4 times over the course of six months and has gone away after a few days until now. No symptoms of other issues, just the code and loss of cruise. A few questions. Is it worth trying to replace O2 sensor first to...

    Hi ladies and gentlemen, I need help finding UEL headers for my 07 NA Forester 2.5X. I'm not looking for big performance or an ear rape exhaust, I just want that Subaru rumble. That's one of the reasons for buying the car, the Subaru rumble. I've been looking online for days for headers that...
  15. Forester Shopping
    Hi folks, just test drove a 2017 forester limited with about 50k miles on it. Couple issues: it smells a bit smoky, the AC is nonexistent, and the dealer replaced the catalytic converter when they took it in. The dealer is prepared to do ozone treatment (hadn't been done) for the smoke and...

    Question for anyone who might have some advice: I love Foresters...now on my second one, an '07 2.5X. It's a manual and it's been really good to me these past few years... BUT, it's needed work recently and now I need help. There was a P0420 code that kept coming back, so my mechanic put in a...
