The product is exactly what it was described to be. My truck runs much better, and no check engine light. Very pleased with Walker products. Quality at a decent price.

OE quality,$500 cheaper than any auto parts store and $2000 cheaper than the dealership. I recommend these to anyone who needs them.

It said direct fit but on this end of catalytic it was not exactly like the one I had. I had to go to auto parts and guy gasket seal to put over where the round ring goes since it had no grooves.

Great part. Better than the OEM. The O2 sensor ports are moved slightly for easier installation.

Installed for an 07 tahoe. The specs say "oem flange" which is a huge lie. It is not near the same thickness, and it also does not use the oring style gasket like oem, uses a flat gasket that is not included. Install the first time went okay, fit up was okay, but starting it up the first time resulted in a huge exhaust leak. I called support and they claimed there have never been any recorded issue with this...which I know is a lie because there are several reviews claiming the same issue.I had to remove from the truck and one of the o2 sensors got wrecked because the hole and weld bound up the sensor. I have all the proper tools and have done this job on several trucks before, just so you know I'm not incompetent. I ended up buying another brand new gasket, bending the flange back as far as possible, putting a new o2 sensor in, added copper gasket spray and reinstalling again.It doesn't leak now, but I'm not sure how long the cats will last. Of course it says it has a warranty, but only if it's installed by a qualified shop. Save yourself about 6 additional hours of hassle and just buy the oem system. Buy once, cry once, I wish I would have gone oem.
