Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451211. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed to fit the 2003-2006 Chevrolet Express 1500, 2003-2006 GMC Savana 1500, and additional vehicles. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Great value
Size: 18-26 Expedition, 15-26 F-150, 18-26 Navigator
The engine air filter fit perfect. The cabin air filter was a bit of a challenge fitting. seemed to be a bit larger but it went in and got the cap back on the box. For the price you cant beat it. Would buy again!

Great Filter Set for Allergy‑Sensitive Families and MPG‑Minded Drivers
Size: 21-25 TLX, 18-25 Odyssey
I bought this set because I prefer handling routine maintenance myself, especially cabin and engine air filters, rather than paying dealership prices for simple jobs. The package included one cabin air filter and one engine air filter, plus a full backup set for the next service interval. Both filters installed easily and fit the 2018 Honda Odyssey exactly as expected. No trimming, no forcing, and no alignment issues. The cabin filter seated cleanly in the glove‑box housing, and the engine filter dropped into the airbox without any airflow restriction or sealing gaps. This setup is ideal for Odyssey owners who want to maintain optimal cabin air quality—especially helpful for families with allergies—and for drivers looking to keep engine airflow unrestricted for the best possible MPG and throttle response. It may not be necessary for anyone who relies exclusively on dealership service or doesn’t perform their own maintenance. Overall, this is a straightforward, high‑value filter set that installs cleanly and supports both air quality and engine efficiency for DIY‑minded Odyssey owners.

Looks good and fits
It looks good and fits perfectly; other than that, I have no idea how to tell if it's better or worse than anything else.
