I purchased a cheap set of catalytic converters on Amazon for about $140. They don’t look nothing like the original as shown in my picture. But after the work of removing the old ones and searching for bolts and gaskets that actually fit I decided after checking the reviews not to use that set because I did not want to repeat the process or removing them if they failed. So I purchased the walker cats and y-pipe.The walker parts were a great fit and my codes all cleared…however a week or 2 later I stated to get o2 sensor codes, a bunch of other errors. And my car was not always starting. Some days it would hesitate. I was stressed that it might have been the walker cats I had purchased to replace both my front and rear cats. But a buddy of mine said it could be the o2 sensor.I had replaced all four on my 2011 chevy traverse and even tested the ohms and voltage. But the one that kept showing an error code the most was the bank 1 sensor 1. So instead of purchasing another cheap sensor I got an OEM for about $180 and that fixed everything.But as other reviews show this is not always an easy job on older rust-buckets and it can take a lot of time to remove broken bolts or stubborn o2 sensors if you want to reuse them. Do not use cheap or common catalytic converters nor the gaskets, bolts and screws that come with them!! You get what you pay for!

Do not buy...it will fail within a few months and there is no warranty whatsoever to get a free replacement. Buy the Magnaflow cats from local Autozone they have them for around same price as these are priced...good luck. I sure learned the hard way now out about $2k.

Product failed & first being told that I must return it to Amazon even though its under Warranty, though Amazon site will not allow me to pro ess a return. The Walker rep than told me that this Fed converter will throw off Check Engine light. After 2001 car makers made dual platforms for cat converters & only in CARB states did you need a CARB unit when replacing faulty one.Follow up with Amazon & Walker horrible. Amazon customer service is off shore & not trained at all in dealing w/warranties. Walker warranty group just as incompetent & useless, refusing to resolving issue with their defective product.Do not buy this part. Lasts 2 years. Amazon & Walker do not stand behind their product as seller and manufacturer.

I bought this off Amazon to save money because the auto shop was wanting to charge me $800 for it. Found a shop that was willing to install outside parts and saved a lot of money. After about 1000 miles, the check engine light did come back on but only for a couple of days and then it turned off again so beware it may take a while to break it in a bit.

I bought cheap cats a few months ago and they worked for two weeks then same codes and misfires.Due to financial struggles I had to change the cats myself. Anyone can tell you changing two cats is not a job you want to do twice. These are worth every penny.Only problem was the bolt holes were too small and nonbolts came with it. For the money you charge guys throw in the bolts
