Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 49321. 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. Designed to fit the 2001-2004 Nissan Pathfinder and 2001-2003 Infiniti QX4, this direct-fit catalytic converter also interchanges with OE parts B08A0-5W500, B08A0-4W100, among others. Avoid potential exhaust leaks by using the included gaskets to get a proper seal.

Nice bed
Color: Blue, Size: Large (Pack of 1)
Good quality dog bed. My pittie loves to burrow himself under blankets so I figured we would give this a try. He hasn’t figured it out yet but it’s his new favorite spot to take a nap when he’s not on our lap. Love the color and seems to be nicely made. I do wish it came in a bigger size but it’s still big enough for him.

Nice quality bed

Nice quality. My dog loves laying on this bed but hasn’t yet figured out getting inside. I cover him after he lays and he seems to enjoy it

Cozy Bed, Just Needs Fluffing
Color: Blue, Size: Large (Pack of 1)
Our dog took to this bed pretty quickly and seems to like curling up under the cave cover. It’s soft, roomy, and gives that little tucked-in feeling a lot of pets seem to love. The cover doesn’t always stay perfectly shaped, so I have to fluff it back up now and then. Other than that, it looks nice in the corner and seems comfortable enough for daily naps. Solid bed overall, especially for the price.

NOT WATERPROOF OR MACHINE WASHABLE
Color: Blue, Size: Large (Pack of 1)
Until today, I would have given this bed 5 stars. When I was looking for a new pet bed, I searched for “waterproof” and “machine washable”. My bad for not verifying those attributes before purchasing as I have learned Amazon search results are not reliable. Today one of my dogs peed on the floor and dragged his bed over it. When I discovered it, I wasn’t concerned because it is waterproof and machine washable. Uh, no it is not. The cushion was wet and was too big to adequately fit in my washer and I could tell the fabric wouldn’t hold up so I hand washed in the tub. But by this evening it was still pretty wet so I tossed it in the dryer on low - by itself - to get the damp out. Well, when I took it out, the cushion had ripped open. Meanwhile, I put the cover in the washing machine. It washed okay, but the plastic part that helps the the opening stay open came out and broke. I cannot find a hole to attempt to put it back in. I am really irritated that it isn’t better made.
