Reviews of WALKER catalytic converter

If out of warranty,WALKER brand is good for replacement, skip the well known high advertised brands, higher price does not equate to better.

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.

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