Owner reviews for catalytic converter

You can get a Walker brand catalytic converter on Rockauto for around $300. It's an exact fit for the crown vic or grand marquis. I paid a shop $150 to install it. They wanted to see the part first, to make sure it wasn't hollow or some junk. These are legit, and I've had it on one of my Grand Marquis for two years so far. The old one was rattling and blocking the exhaust.

FWIW - I daily my v8 R and it’s awesome. Mine is still under original warranty, it did have the cat fail which was covered under warranty and would have been pricey otherwise.

I recently bought an 86 and got it CA smogged after it sat for 10 years. Did a rebuilt kit for the stock carb, Walker Hitachi DFB306. Had to get a new CA compliant cat which I went with the Magnaflow 339104.

Just installed a rebuilt c60, mwr fly wheel, and exedy clutch. Mwr lightweight alternator pulley and alternator. Kyb suspension. T3 sway bar and control arms. Magnaflow cat. S2000 seats. Breast plate bracing And a bunch of oem replacement parts to pass smog. 2000 mr2 spyder

My daughter has a 2017, she loves it. 150+K miles... NOTHING major ever with it. Recently, she's been getting a catalytic converter code. Keep up on maintenance it should be good.

Cat went out, so I got a high flow, ported and polished, cammed, and tuned the 2.slow to make…. 127whp……. A FOURTY HORSEPOWER INCREASE….. and nearly unheard of for an AEG……

apparently they ruin their cat converters, mines just had its 3rd one fitted, 94k miles and no real problems so far, but the savings in road tax make up for it assuming you get a good unit.

I'd be hesitant to go aftermarket due to my own experience with a Walker cat going bad in 2 months on my VW.

I would cut your losses now. I ate the negative equity on my Tucson after going through 3 catalytic converters in 6 months.

Dumb thing threw a check engine light on while driving home from the shady used car dealer. Threw a bunch of parts at it to try and fix the misfiring issue, only to give up and have a shop diagnose it who told me that one of the cats was not smog legal.
