  1. New Rear Catalytic Converter

    Problems & 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...

  6. Cracked catalytic converter

    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...
