Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-172. 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 specifically for the 2009-2016 BMW Z4 and interchanges with OE part 18 30 7 647 051. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Large adult aggressive chewer? No. Puppy? Yes
Pattern Name: Classic Squeaky Tug
My large adult dog who is an aggressive chewer got this toy in pieces within minutes, BUT this is a great toy for a lighter touched dog. When I got my newest addition (Malinois mix puppy. Pls thoughts and prayers for me), this toy came to mind because she loves chewing and she’s only 11 weeks old! She needed an interesting toy that is sturdy and won’t hurt her teeth or gums, but is still interesting (the rope piece and the squeaker). She’s not nearly as rough of a chewer as my older guy YET. But when she gets bigger, she will more than likely destroy this. She is almost 20lbs at 11 weeks right now, so I will update if she does destroy it. Long story short: Not good for large aggressive chewers, good for aggressive chewers on the smaller side (maybe 15-30lbs)

Great toy!!
Pattern Name: Classic Squeaky Tug
Love, LOVE, LOOOVVVEEE this toy!! Finally, an actual indestructable toy for my super chewer!! As others have said, the little rope thing came off in less than an hour, LOL. But the 'Corn cob' is great!! My baby LOVES this thing and chews on it constantly and it shows no sign of wear!! I am optmistic that it will actually last more than a month.
