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 super chewers
Color: Hambone Super Chewer, Size: M/L
Had to take it away from my dog the same evening I gave it to him because a chunk came off. I did not want him to choke on the pieces.

A favorite for my boys!
Color: Hambone Super Chewer, Size: M/L
My dogs love this toy, it satisfied their need to rip up a toy and still allowed them to play long after the top layer was torn apart to enjoy! It bounces well and has still held up with my chewers, this is still one of my dogs favorite toys to play fetch with!

Great toy
Color: Hambone Super Chewer, Size: M/L
My dog loves this toy so much. He's not quite so aggressive with his chewing, now that he's getting older, but this toy lasted through his younger years, and recently started to show signs of wear. He was so sad when I threw it out, that I had to replace it. Glad it still exists - we got the first one probably 5 years ago.

Great for heavy chewers
Color: Hambone Super Chewer, Size: M/L
Our dog is a hard core chewer! This toy is very durable. Even the covering has lasted. We assumed we would need to take the cover off right away but it’s still going after 3 months. It’s definitely chew resistant

Great treat dispenser
Color: Hambone Super Chewer, Size: M/L
Great rubber toy, the outside fabric did not last long, so glad that it is a treat holder/dispenser otherwise it would have been done for in about 10min. The opening for the treats is pretty small so can only fight thinner broken up treats. Great for larger dog that likes to dissect her toys, keeping her entertained longer and no fluff all over the house
