Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 52173. 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 2008-2012 Mercedes-Benz GL550, 2008-2011 Mercedes-Benz ML550, and more, this direct-fit catalytic converter also interchanges with OE parts 164 490 51 36, 164 490 52 36, among others.

Amazing and cute
Size: Small, Color: Pink, Size: Small, Color: Pink
I have a puppy who absolutely adores her toys, especially now that she’s teething! I picked out some pink ones that are just right for her—she’s only 2 1/2 months old and weighs 2 lbs. The best part is the variety of toys she loves to play with.
