Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 49871. 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 2004-2009 Audi S4 and interchanges with OE parts 8E0 254 505 RX and 8E0 254 502 TX. Hardware is included to eliminate the hassle of working with corroded factory parts.

Not for chewers
Size: 8 Inch, Color: Yellow, Size: 8 Inch, Color: Yellow
My dog managed to pop this and completely chew through it in a matter of 4 days. It was definitely cute and she loved the size of it but with her chewing all the way to the core we have to get rid of it. I thought it was a good material but I guess I was wrong. Kind of sad considering the money spent only lasted 4 days

Great dog toy
Size: 8 Inch, Color: Pink
The amount of stupid and cute these dogs look like when they shake this ball and smack their own faces! It took a hot second for either dog to understand where to bite on the ball, but now that they do, they both will play with it for a while. Great purchase, came with a pump to blow the ball up.

Love these! They are good quality and my dogs love them so much actually I ordered a second set for my sister's dogs and they love them as well! Great buy for the price! I'm sure I will be buying some more but thankfully it isn't one week later because they are sturdy!

Heavy chewers can't break these alone.
Style: 5 Pcs No Stuffing Basic
These toys are AWESOME! As long as you don't get tricked into playing tug of war with them, they will last a very long time (almost 2 months) with a heavy chewer that tears through most toys in a couple hours. The tug pressure rips a seam. Then, that portion is a goner. However, the rest of the toy stays intact.

Well made & my dog LOVES them!
Style: 5 Pcs No Stuffing Basic
Great value for FIVE very cute and well made stuff-less toys with crinkly paper inside and TWO squeakers each. My dog loves playing with them! I have two in his toy box and put three up to save for later for backup if/when he destroys the first two. 😂 I love the cute and unique designs of the squirrel, donkey, fox, cow, and giraffe, too.
