Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51578. 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 2009-2013 Chevrolet Silverado 1500, 2009-2013 GMC Sierra 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.

Fun toy but not as durable as I hoped.
Color: Green
I just rescued a dog from the shelter. She is super sweet and playful but she loves to chew her toys so I needed to buy her ones more durable to play with. This toy caught my eye but I was concerned that it might be too large for my small 7 pound terrier mix. After receiving it, I really loved the colors and the way it looked and my dog loves playing with it. Everything about it is great except that within a few weeks of playing with it, she already managed to make a small tear in it. It's not to the point where I would take it away from her toy box but I just wish it was more durable.

Great for tug of war
Color: Green
All the arms make for a good tug of war toy. It’s tough enough that my 70 lbs lab can pull on it and it’s fine

Durable
Color: Green, Color: Green
We’ve had it for awhile now and it’s still (mostly) in one piece. Has held up well for our heavy chewing puppy. It lost a tentacle but that’s nothing compared to the level of destruction our dog has put other toys through in much shorter amounts of time. Recommend for heavy chewers and will likely buy again!

Not large
Color: Green
This is a lot smaller than it appears in pictures. I was going to give it to a large dog but I’m worried it would be a choking hazard. instead I’m going to give it to a pug. Seems fine quality wise just not “large”
