First, know that Amazon has taken good care of me on the problems I am about to relate. So, that got this review to 3 stars, otherwise, it would be 1 or 0. This Pulcherflow kit was purchased in mid-March for a 2012 Honda Odyssey minivan whose diagnostic codes showed that two of the three catalytic converters had "gone bad."I found and purchased this three catalytic converter (cat) kit because, did I mention it yet... this vehicle has THREE cats! Facing the engine compartment, they are installed 1) on the front of the engine, 2) on the back of the engine, and 3) under the van and behind the engine.Only cat 1 of this kit was actually install-able. Cat 2 had a factory defect - a cross-threaded O2 sensor port that would not have held pressure under normal operating conditions. Cat 3 was the right shape, but the rearmost mounting flange was rotated 90 degrees out-of-phase with the vehicle's configuration! Not my definition of compatible!I did the obvious and reported the defect to Amazon, and ordered replacement parts online, delaying the completion of my vehicle repairs by 1 week. When the replacement parts arrived... what a joke! What was sent was some of dashboard screen protector for a Hyundai. Could be a legit pick-and-pull error, but the 3 cat box was nearly a 1 foot cube and weighed #35! The screen protectors weren't even 1 pound and came in a long, narrow box about 1" thick!!So, an Easter Sunday morning(!) call to Amazon Support revealed that they've got some GREAT customer service reps willing to work on holidays!!! ...and the 3 cat kit was out-of-stock. Well, of course it was, because my vehicle was sitting in a mechanic's garage in pieces waiting for the parts.Now remember! I said that Amazon is taking *good* care of me. They are making an appropriate refund and paying to ship back the unused and incorrect/damaged parts. Which is good, because a quicker than end-of-May replacement cat #2 cost me more $100 more than the whole 3 cat kit did in the first place.I got my van back today - Apr 2. Amazon's site no longer even shows the listing for these cats for Honda Odyssey vans. So, save yourself some trouble and just buy the one you need from O'Reilly's. Dorman makes a good part with a lifetime warranty! And keep in mind, you are looking for "drop-in" or "bolt-on" in the item description - "compatible with" may not be!Thank Amazon for taking good care of a long-time customer.

These cats work perfectly fine. I was a bit skeptical about these but after installing them I had no issues, no check engine light or nothing. I can even feel a little bit of power increment, after replacing the 236K miles old cats. These are great for the money. Happy with my purchase.

Liked the fast shipping. Didn't like that the rear cat did not line up properly. I didn't try bank 1 or 2. My car is a 2011 Accord V6 3.5L coupe. Exhaust pipe could have been cut, rotated and re-welded but I already had it apart at my house. Had to reinstall.
