A-Premium Front Left Catalytic Converter Kit Direct-Fit Compatible with Chevrolet Impala 2014-2018 & Cadillac XTS 2013-2016, 3.6L, EPA Compliant

2016 impala front catalytic. Perfect fit.

Product was a perfect fit for my 2016 Cadillac XTS. Didn’t have a heat shield like the old one dead, not sure that it matters.

The product was perfect no issues

It looks (and is) a perfect match to the factory one, minus the heat shield. The fitment is perfect (the cheap ones have nuts and bolts for the exhaust pipe, this one has threaded holes on the flange like the original.) Appears to be well made, but after about 2 months, I got a MIL light and sure enough, it was complaining about the converter being below it's efficiency rating.If you have a scanner, you can watch the pre and post oxygen sensor voltages; if they look like they almost match in a graph, it's dead. The post should be "smoothed out" by comparison. To get a feel of how it should look, compare the pre/post sensor voltages in a graph for bank 1 (this converter is for bank 2, which is the one that gets the cracks in the flange and leaks - most likely why you're buying it.)Just a side note, I have brand new O2 sensors on it as well so it's not my sensors going bad. When you replace this, make sure you're not experiencing other issues like misfires - if you have over 100k miles, you should change your spark plugs (be sure to get the recommended type, like iridium.) Go ahead and replace both oxygen sensors too, so you know that isn't causing issues either. (Oxygen sensors are one of the most overlooked parts on a car and should be replaced every 50k miles!)I have a sneaking suspicion that wherever these converters are made, they aren't fully coating the substrate with enough catalyst (as that's the truly expensive part.) As such, they aren't as efficient and fail early at the first sign of even the tiniest bit of buildup. That's how they're made so cheap.

Perfect fit for my 2013 Cadillac XTS. This catalytic converter is a great replacement for the converter located just behind the radiator. Tip: You may need to remove the oil filter to better position old cat in order to access bottom bolts. Bottom bolts are best accessed from under the vehicle by removing undercarriage cover.

Replaced on a 2017 Chevy Impala and only worked for 2 months.

The price, delivery, and transaction overall was awesome. The part was an exact fit and works perfectly for my vehicle. I will definitely shop with this seller again in the future.

Catalytic converter last me 10months for my Chevy impala 2017!!! Keeps giving P0430 code with a lil rough idle!
